The metabolic process of all living cells (animal and plant) in which oxygen is used to provide a source of energy for the cell.
The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346)
Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes. (King & Stansfield, A Dictionary of Genetics, 4th ed)
A multisubunit enzyme complex containing CYTOCHROME A GROUP; CYTOCHROME A3; two copper atoms; and 13 different protein subunits. It is the terminal oxidase complex of the RESPIRATORY CHAIN and collects electrons that are transferred from the reduced CYTOCHROME C GROUP and donates them to molecular OXYGEN, which is then reduced to water. The redox reaction is simultaneously coupled to the transport of PROTONS across the inner mitochondrial membrane.
An element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.
A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration (= OXYGEN CONSUMPTION) or cell respiration (= CELL RESPIRATION).
An abnormal pattern of breathing characterized by alternating periods of apnea and deep, rapid breathing. The cycle begins with slow, shallow breaths that gradually increase in depth and rate and is then followed by a period of apnea. The period of apnea can last 5 to 30 seconds, then the cycle repeats every 45 seconds to 3 minutes.
Electron transfer through the cytochrome system liberating free energy which is transformed into high-energy phosphate bonds.

Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix. (From Alberts et al., Molecular Biology of the Cell, 2d ed, p343-4)
Anaerobic degradation of GLUCOSE or other organic nutrients to gain energy in the form of ATP. End products vary depending on organisms, substrates, and enzymatic pathways. Common fermentation products include ETHANOL and LACTIC ACID.
A metabolic process that converts GLUCOSE into two molecules of PYRUVIC ACID through a series of enzymatic reactions. Energy generated by this process is conserved in two molecules of ATP. Glycolysis is the universal catabolic pathway for glucose, free glucose, or glucose derived from complex CARBOHYDRATES, such as GLYCOGEN and STARCH.
Agents used to prevent or reverse the pathological events leading to sickling of erythrocytes in sickle cell conditions.
The collective designation of three organizations with common membership: the European Economic Community (Common Market), the European Coal and Steel Community, and the European Atomic Energy Community (Euratom). It was known as the European Community until 1994. It is primarily an economic union with the principal objectives of free movement of goods, capital, and labor. Professional services, social, medical and paramedical, are subsumed under labor.

Role of hypoxia-induced Bax translocation and cytochrome c release in reoxygenation injury. (1/1245)

We investigated mechanisms of cell death during hypoxia/reoxygenation of cultured kidney cells. During glucose-free hypoxia, cell ATP levels declined steeply resulting in the translocation of Bax from cytosol to mitochondria. Concurrently, there was cytochrome c release and caspase activation. Cells that leaked cytochrome c underwent apoptosis after reoxygenation. ATP depletion induced by a mitochondrial uncoupler resulted in similar alterations even in the presence of oxygen. Moreover, inclusion of glucose during hypoxia prevented protein translocations and reoxygenation injury by maintaining intracellular ATP. Thus, ATP depletion, rather than hypoxia per se, was the cause of protein translocations. Overexpression of Bcl-2 prevented cytochrome c release and reoxygenation injury without ameliorating ATP depletion or Bax translocation. On the other hand, caspase inhibitors did not prevent protein translocations, but inhibited apoptosis during reoxygenation. Nevertheless, they could not confer long-term viability, since mitochondria had been damaged. Omission of glucose during reoxygenation resulted in continued failure of ATP production, and cell death with necrotic morphology. In contrast, cells expressing Bcl-2 had functional mitochondria and remained viable during reoxygenation even without glucose. Therefore, Bax translocation during hypoxia is a molecular trigger for cell death during reoxygenation. If ATP is available during reoxygenation, apoptosis develops; otherwise, death occurs by necrosis. By preserving mitochondrial integrity, BCL-2 prevents both forms of cell death and ensures cell viability.  (+info)

Beneficial effects of raxofelast (IRFI 016), a new hydrophilic vitamin E-like antioxidant, in carrageenan-induced pleurisy. (2/1245)

1. Peroxynitrite is a strong oxidant that results from reaction between NO and superoxide. It has been recently proposed that peroxynitrite plays a pathogenetic role in inflammatory processes. Here we have investigated the therapeutic efficacy of raxofelast, a new hydrophilic vitamin E-like antioxidant agent, in rats subjected to carrageenan-induced pleurisy. 2. In vivo treatment with raxofelast (5, 10, 20 mg kg(-1) intraperitoneally 5 min before carrageenan) prevented in a dose dependent manner carrageenan-induced pleural exudation and polymorphonuclear migration in rats subjected to carrageenan-induced pleurisy. Lung myeloperoxidase (MPO) activity and malondialdehyde (MDA) levels, as well as histological organ injury were significantly reduced by raxofelast. 3. Immunohistochemical analysis for nitrotyrosine, a footprint of peroxynitrite, revealed a positive staining in lungs from carrageenan-treated rats. No positive nitrotyrosine staining was found in the lungs of the carrageenan-treated rats, which received raxofelast (20 mg kg 1) treatment. 4. Furthermore, in vivo raxofelast (5, 10, 20 mg kg(-1)) treatment significantly reduced peroxynitrite formation as measured by the oxidation of the fluorescent dihydrorhodamine 123, prevented the appearance of DNA damage, the decrease in mitochondrial respiration and partially restored the cellular level of NAD+ in ex vivo macrophages harvested from the pleural cavity of rats subjected to carrageenan-induced pleurisy. 5. In conclusion, our study demonstrates that raxofelast, a new hydrophilic vitamin E-like antioxidant agent, exerts multiple protective effects in carrageenan-induced acute inflammation.  (+info)

Cytosolic Ca2+ movements of endothelial cells exposed to reactive oxygen intermediates: role of hydroxyl radical-mediated redox alteration of cell-membrane Ca2+ channels. (3/1245)

1. The mode of action of reactive oxygen intermediates in cysosolic Ca2+ movements of cultured porcine aortic endothelial cells exposed to xanthine/xanthine oxidase (X/XO) was investigated. 2. Cytosolic Ca2+ movements provoked by X/XO consisted of an initial Ca2+ release from thapsigargin-sensitive intracellular Ca2+ stores and a sustained Ca2+ influx through cell-membrane Ca2+ channels. The Ca2+ movements from both sources were inhibited by catalase, cell-membrane permeable iron chelators (o-phenanthroline and deferoxamine), a *OH scavenger (5,5-dimethyl-1-pyrroline-N-oxide), or an anion channel blocker (disodium 4, 4'-diisothiocyano-2, 2'-stilbenedisulphonic acid), suggesting that *O2- influx through anion channels was responsible for the Ca2+ movements, in which *OH generation catalyzed by intracellular transition metals (i.e., Haber-Weiss cycle) was involved. 3. After an initial Ca2+ elevation provoked by X/XO, cytosolic Ca2+ concentration decreased to a level higher than basal levels. Removal of X/XO slightly enhanced the Ca2+ decrease. Extracellular addition of sulphydryl (SH)-reducing agents, dithiothreitol or glutathione, after the removal of X/XO accelerated the decrement. A Ca2+ channel blocker, Ni2+, abolished the sustained increase in Ca2+, suggesting that Ca2+ influx through cell-membrane Ca2+ channels was extracellularly regulated by the redox state of SH-groups. 4. The X/XO-provoked change in cellular respiration was inhibited by Ni2+ or dithiothreitol as well as inhibitors of Haber-Weiss cycle, suggesting that Ca2+ influx was responsible for *OH-mediated cytotoxicity. We concluded that intracellular *OH generation was involved in the Ca2+ movements in endothelial cells exposed to X/XO. Cytosolic Ca2+ elevation was partly responsible for the oxidants-mediated cytotoxicity.  (+info)

Myogenin induces a shift of enzyme activity from glycolytic to oxidative metabolism in muscles of transgenic mice. (4/1245)

Physical training regulates muscle metabolic and contractile properties by altering gene expression. Electrical activity evoked in muscle fiber membrane during physical activity is crucial for such regulation, but the subsequent intracellular pathway is virtually unmapped. Here we investigate the ability of myogenin, a muscle-specific transcription factor strongly regulated by electrical activity, to alter muscle phenotype. Myogenin was overexpressed in transgenic mice using regulatory elements that confer strong expression confined to differentiated post-mitotic fast muscle fibers. In fast muscles from such mice, the activity levels of oxidative mitochondrial enzymes were elevated two- to threefold, whereas levels of glycolytic enzymes were reduced to levels 0.3-0.6 times those found in wild-type mice. Histochemical analysis shows widespread increases in mitochondrial components and glycogen accumulation. The changes in enzyme content were accompanied by a reduction in fiber size, such that many fibers acquired a size typical of oxidative fibers. No change in fiber type-specific myosin heavy chain isoform expression was observed. Changes in metabolic properties without changes in myosins are observed after moderate endurance training in mammals, including humans. Our data suggest that myogenin regulated by electrical activity may mediate effects of physical training on metabolic capacity in muscle.  (+info)

Mitochondrial group II introns, cytochrome c oxidase, and senescence in Podospora anserina. (5/1245)

Podospora anserina is a filamentous fungus with a limited life span. It expresses a degenerative syndrome called senescence, which is always associated with the accumulation of circular molecules (senDNAs) containing specific regions of the mitochondrial chromosome. A mobile group II intron (alpha) has been thought to play a prominent role in this syndrome. Intron alpha is the first intron of the cytochrome c oxidase subunit I gene (COX1). Mitochondrial mutants that escape the senescence process are missing this intron, as well as the first exon of the COX1 gene. We describe here the first mutant of P. anserina that has the alpha sequence precisely deleted and whose cytochrome c oxidase activity is identical to that of wild-type cells. The integration site of the intron is slightly modified, and this change prevents efficient homing of intron alpha. We show here that this mutant displays a senescence syndrome similar to that of the wild type and that its life span is increased about twofold. The introduction of a related group II intron into the mitochondrial genome of the mutant does not restore the wild-type life span. These data clearly demonstrate that intron alpha is not the specific senescence factor but rather an accelerator or amplifier of the senescence process. They emphasize the role that intron alpha plays in the instability of the mitochondrial chromosome and the link between this instability and longevity. Our results strongly support the idea that in Podospora, "immortality" can be acquired not by the absence of intron alpha but rather by the lack of active cytochrome c oxidase.  (+info)

Oxygen-dependent inhibition of respiration in isolated renal tubules by nitric oxide. (6/1245)

BACKGROUND: The partial pressure (tension) of oxygen (PO2) in the kidney medulla has been established to be lower than that of the cortex. The kidney medulla has been shown to be particularly sensitive to hypoxia. However, the measured PO2 in the kidney medulla is sufficient to support maximal respiration. It has been recently shown that endogenously produced nitric oxide (NO) may inhibit oxygen consumption in the kidney. We studied whether NO plays a role in hypersensitivity of the kidney medulla to hypoxia. METHODS: We studied the effect of added NO on isolated cortical and outer medullary renal tubules in simultaneous oxygen consumption and NO measurements at different oxygen concentrations. RESULTS: We found that NO could potently and reversibly inhibit respiration at nanomolar concentrations. The inhibitory effect of NO was markedly increased at low physiological oxygen concentrations. The effect of NO was cGMP independent because the selective guanylyl cyclase inhibitor 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) at a 10 microM concentration had no effect on basal or NO-inhibited respiration. The value for half-maximal NO-mediated inhibition of respiration was virtually identical to that found in isolated mitochondria, and therefore, NO was most likely directly acting on mitochondria. Interestingly, we found no differences in sensitivity to NO-mediated inhibition between outer medullary and cortical tubules. CONCLUSIONS: We suggest that because of its low PO2, the renal outer medulla is more sensitive to hypoxia, not because of the low PO2 as such, but probably because of the competition between NO and oxygen to control respiration.  (+info)

Declines in mitochondrial respiration during cardiac reperfusion: age-dependent inactivation of alpha-ketoglutarate dehydrogenase. (7/1245)

We previously reported that cardiac reperfusion results in declines in mitochondrial NADH-linked respiration. The degree of inactivation increased with age and was paralleled by modification of protein by the lipid peroxidation product 4-hydroxy-2-nonenal. To gain insight into potential sites of oxidative damage, the present study was undertaken to identify specific mitochondrial protein(s) inactivated during ischemia and reperfusion and to determine which of these losses in activity are responsible for observed declines in mitochondrial respiration. Using a Langendorff rat heart perfusion protocol, we observed age-dependent inactivation of complex I during ischemia and complex IV and alpha-ketoglutarate dehydrogenase during reperfusion. Although losses in complex I and IV activities were found not to be of sufficient magnitude to cause declines in mitochondrial respiration, an age-related decrease in complex I activity during ischemia may predispose old animals to more severe oxidative damage during reperfusion. It was determined that inactivation of alpha-ketoglutarate dehydrogenase is responsible, in large part, for observed reperfusion-induced declines in NADH-linked respiration. alpha-Ketoglutarate dehydrogenase is highly susceptible to 4-hydroxy-2-nonenal inactivation in vitro. Thus, our results suggest a plausible mechanism for age-dependent, reperfusion-induced declines in mitochondrial function and identify alpha-ketoglutarate dehydrogenase as a likely site of free radical-mediated damage.  (+info)

Respiratory uncoupling induces delta-aminolevulinate synthase expression through a nuclear respiratory factor-1-dependent mechanism in HeLa cells. (8/1245)

Nuclear respiratory factor (NRF)-1 appears to be important for the expression of several respiratory genes, but there is no direct evidence that NRF-1 transduces a physiological signal into the production of an enzyme critical for mitochondrial biogenesis. We generated HeLa cells containing plasmids allowing doxycycline-inducible expression of uncoupling protein (UCP)-1. In the absence of doxycycline, UCP-1 mRNA and protein were undetectable. In the presence of doxycycline, UCP-1 was expressed and oxygen consumption doubled. This rise in oxygen consumption was associated with an increase in NRF-1 mRNA. It was also associated with an increase in NRF-1 protein binding activity as determined by electrophoretic mobility shift assay using a functional NRF-1 binding site from the delta-aminolevulinate (ALA) synthase promoter. Respiratory uncoupling also caused a time-dependent increase in protein levels of ALA synthase, an early marker for mitochondrial biogenesis. ALA synthase induction by respiratory uncoupling was prevented by transfecting cells with an oligonucleotide antisense to the region of the NRF-1 initiation codon; a scrambled oligonucleotide with the same base composition had no effect. Respiratory uncoupling increases oxygen consumption and lowers energy reserves. In HeLa cells, uncoupling also increases ALA synthase, an enzyme critical for mitochondrial respiration, but only if translatable mRNA for NRF-1 is available. These data suggest that the transcription factor NRF-1 plays a key role in cellular adaptation to energy demands by translating physiological signals into an increased capacity for generating energy.  (+info)

Introduction. QUEST LAB-PART II: SHOW WHAT YOU KNOW INTRODUCTION TO CELLULAR RESPIRATION IN YEAST Cellular respiration is the process where glucose is released as energy in the form of ATP. Cellular respiration occurs in two ways. During anaerobic respiration, energy is produced without oxygen. The fermentation of yeast can occur because the yeast cells have the capability to undergo cellular respiration without the presence of oxygen. Yeast is able to break down sugar into glucose, causing the release of carbon dioxide. During the process of glycolysis, the initial two ATP molecules are what activate the glucose. Two NADH molecules are produced, causing two additional ATP molecules to be produced. Temperature is a factor that affects the rate of cellular respiration in yeast. It alters the amount of energy used as well as the amount of oxygen needed. Since yeast is a living organism, temperature is needed to activate its energy production. When too high a temperature is present, the yeast ...

Aerobic Respiration is the second part of cellular respiration. Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Aerobic means in air, but it is the Oxygen in the air which is necessary for aerobic respiration. This is the part of cellular respiration that most of the ATP is produced. After glycolysis, if oxygen is present in the cells environment, pyruvic acid is broken down and NADH is used to make a large amount of ATP through this process. Oxygen is important to aerobic respiration because oxygen allows additional electrons to pass along the chain and if they didnt ATP synthesis would stop. In aerobic respiration pyruvic acid is converted into Carbon Dioxide and water, producing a large amount of ATP. Aerobic respiration has two major stages known as the Krebs Cycle (named after a German biochemist, Hans Krebs), and the elctron transport chain. In the Krebs Cycle the oxidation of glucose is complete. The Krebs cycle takes 2 ...
Compartmentalization of high-energy phosphate carriers between intracellular micro-compartments is a phenomenon that ensures efficient energy use. To connect these sites, creatine kinase (CK) and adenylate kinase (AK) energy-transfer networks, which are functionally coupled to oxidative phosphorylation (OXPHOS), could serve as important regulators of cellular energy fluxes. Here, we introduce how selective permeabilization of cellular outer membrane and high-resolution respirometry can be used to study functional coupling between CK or AK pathways and OXPHOS in different cells and tissues. Using the protocols presented here the ability of creatine or adenosine monophosphate to stimulate OXPHOS through CK and AK reactions, respectively, is easily observable and quantifiable. Additionally, functional coupling between hexokinase and mitochondria can be investigated by monitoring the effect of glucose on respiration. Taken together, high-resolution respirometry in combination with permeabilization is a
Two mitochondrial mechanisms have been suggested for the development of pressure overload contractile dysfunction: mitochondrial dysfunction through uncoupling or through reduced oxidative phosphorylation capacity due to PGC-1α downregulation.

Most of the reactions in cellular respiration are redox reactions in the presence of strong oxidizing agents like molecular oxygen. Glycolysis is the initial step of glucose metabolism, which is the common pathway in both aerobic and anaerobic respiration. NAD is involved in redox reactions where it becomes reduced by accepting electrons and oxidizes by donating those electrons to other molecules. Besides, other energy-rich molecules like NADH and FADH. Learn how your comment data is processed. Water molecules are also formed during aerobic respiration after the capture of electrons by oxygen molecules.

Scientists think that glycolysis evolved before the other stages of cellular respiration. This is because the other stages need oxygen, whereas glycolysis does not, and there was no oxygen in Earths atmosphere when life first evolved about 3.5 to 4 billion years ago. Cellular respiration that proceeds without oxygen is called anaerobic respiration. Then, about 2 or 3 billion years ago, oxygen was gradually added to the atmosphere by early photosynthetic bacteria. After that, living things could use oxygen to break down glucose and make ATP. Today, most organisms make ATP with oxygen. They follow glycolysis with the Krebs cycle and electron transport to make more ATP than by glycolysis alone. Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration.. ...

Cellular respiration is the process by which food molecules react with oxygen and are broken down to carbon dioxide and water with a net gain of captured energy in the form of ATP molecules. Therefore, it is the conversion of CHEMICAL energy of ORGANIC molecules to METABOLICALLY USABLE energy within living cells. Most of the process occurs within MITOCHONDRIA in EUKARYOTIC cells. All organisms utilize the processes of cellular respiration to provide energy for cellular maintenance and for the production of starting materials for the biosynthesis of needed compounds.. Cellular respiration occurs 24 HOURS/DAY in all organisms. Respiration is sometimes called BIOLOGICAL OXIDATION and thus may be compared to BURNING. Although both are OXIDATION reactions, the manner in which the energy is RELEASED differs in the two processes. In both, the energy released is obtained from CHEMICAL BONDS. CARBON DIOXIDE may be a WASTE PRODUCT in both. In BURNING there is an UNCONTROLLED, rapid release of energy with ...
By definition, cellular respiration is the set of catabolic pathways that break down the nutrients we consume into usable forms of chemical energy (ATP). Cellular respiration can occur both with or without the presence of oxygen, and these two main forms are referred to as aerobic and anaerobic respiration, respectively

The second phase of cellular respiration and ATP creation is even more complicated than glycosis, involving another series of chemical reactions. This phase is termed aerobic respiration, and it must occur in the presence of oxygen. Floating inside the cells cytoplasm are tiny organelles called mitochondria. These organelles perform the function necessary for the occurrence of aerobic respiration. Mitochondria use enzymes as a means of breaking down those chemical substances created during glycosis. The cell then reassembles the resulting atoms into ATP molecules. The cell makes a net of two ATP molecules from each molecule of glucose. The gain is net because cellular respiration itself uses up some of the cells ATP.. ...

The first step in both anaerobic and aerobic respiration is called glycolysis. This is the process of taking one glucose (sugar) molecule and breaking it down into pyruvate and energy (2 ATP). We will discuss this in depth during aerobic respiration.. The second step in anaerobic respiration is called fermentation. Fermentation starts with pyruvate (the end product of glycolysis). Depending on the organism, pyruvate can either be fermented into ethanol (a fancy name for alcohol) or lactate (lactic acid). Fermentation releases CO2, but does not make any ATP - all ATP during anaerobic respiration is produced during glycolysis. Since glycolysis produces 2 ATP, anaerobic respiration yields 2 ATP for every molecule of glucose. Both glycolysis and fermentation take place within the cytosol/cytoplasm of a cell. In fact, the entire process of anaerobic respiration takes place in the cytosol.. Fermentation is the process by which we make wine and other types alcohol. Through an anaerobic process, yeast ...
In reality, theyre so very good at it that they appear in lots of those high energy-vitamin powders the kids are taking nowadays. All living things have to have an unceasing supply of power and matter. They perform high-energy actions like locomotion. If living things could not obtain the energy they want out of food, it would be totally worthless.. Fermentation releases CO, but does not earn any ATP all ATP during anaerobic respiration is created during glycolysis. Breathing is required for the cells to acquire oxygen, but theres much more to respiration, as stated above. Below well discuss how different kinds of organisms perform respiration to generate ATP. As I mentioned, oxygen is essential for the general procedure for cellular respiration. When it isnt possible to acquire enough oxygen, our cells begin to use anaerobic respiration. Aerobic respiration happens when oxygen is available, whereas anaerobic respiration happens when oxygen isnt offered.. essay writer Krebs Cycle is also ...

Cellular respiration or aerobic cellular respiration, is exergonic because energy is released from the reaction and therefor the products have less energy then the starting substance. Because it releases energy. Cellular respiration is a catabolic pathway -- this means it takes bigger molecules (like glucose) and breaks them down into smaller, more stable molecules. Since glucose has more energy than the smaller molecules produced at the end of cellular respiration, there is some extra energy left over, which is then stored in ATP.
Cellular respiration is what cells do to break up sugars to get energy they can use. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain. This produces ATP which supplies the energy that cells need to do work. When they dont get enough oxygen, the cells use anaerobic respiration, doesnt require oxygen. However, this process produces lactic acid, and is not as efficient as when oxygen is used. Aerobic respiration, the process that does use oxygen, produces much more energy and doesnt produce lactic acid. It also produces carbon dioxide as a waste product, which then enters the circulatory system. The carbon dioxide is taken to the lungs, where it is exchanged for oxygen. The simplified formula for aerobic cellular respiration is: ...
en] To study the mechanism of oxygen regulation in inflammation-induced acute kidney injury, we investigate the effects of a bacterial endotoxin (lipopolysaccharide, LPS) on the basal respiration of proximal tubular epithelial cells (HK-2) both by high-resolution respirometry and electron spin resonance spectroscopy. These two complementary methods have shown that HK-2 cells exhibit a decreased oxygen consumption rate when treated with LPS. Surprisingly, this cellular respiration alteration persists even after the stress factor was removed. We suggested that this irreversible decrease in renal oxygen consumption after LPS challenge is related to a pathologic metabolic down-regulation such as a lack of oxygen utilization by cells ...

The understanding on the contribution of root respiration to total soil respiration is still very limited, especially for sugarcane. In this study, trenching experiments in sugarcane plantations were conducted to separate and investigate soil respiration for this crop. The measurements were performed for the whole growing period of 344 days to quantify root respiration. The obtained monitoring data showed that the respiration rate is increasing with the age of the plant, accounting for up to 29% of the total soil respiration before harvesting. The root to soil respiration ratio increased rapidly during the young seedling stage, i.e. first five months, then declined and finally got stabilized during yield formation and ripening stages, respectively. In addition, the results from the measurements confirmed that soil respiration was positively correlated with soil moisture content.
Introduction. Name: Wesley Towstik LAB: THE EFFECT OF EXERCISE ON CELLULAR RESPIRATION Introduction: Cellular respiration is the process that cells use to break down glucose; this releases energy that is used to produce ATP. Cellular respiration involves a series of enzyme-catalysed reactions. The equation below shows the complete oxidation of glucose during aerobic cellular respiration. Oxygen is required for this energy-releasing process to occur. C6H12O6 + 6O2 --, 6CO2 + 6H2O + 686 kilocalories of energy/mole of glucose oxidized By studying the equation above, you will notice there are three ways cellular respiration could be measured. One could measure the: 1.Consumption of O2 2. Production of CO2 3. Release of energy during cellular respiration1 In this experiment the relative rate of CO2 production will be measured. Bromthymol blue (BTB) is an indicator that turns yellow in the presence of an acid. Since CO2 combines with H2O to produce carbonic acid, BTB can be used to detect the presence ...

Using the C2C12 mouse muscle myoblast cell line, I sought to investigate the hypothesis that differentiation under hypoxia impairs muscle mitochondrial respiratory function irreversibly. Resveratrol (RSV) will increase expression of markers of mitochondrial biogenesis and reverse the hypoxia-induced depression of O2 consumption rates. Hypoxia decreased oxygen consumption rates after five days of differentiation and after two days of normoxic recovery. This coincided with a hypoxia-induced decrease in protein levels of the NDUFB8 subunit of complex I of the electron transport chain and decreases in mRNA levels of mitochondrial biogenesis transcription factors, both of which could contribute to the alterations observed in oxygen consumption rates. Normoxic recovery supplemented with RSV did increase oxygen consumption rates, however this increase was not observed across all oxygen concentrations that were measured which may have be associated with the decreases in cell viability observed with RSV
The effects of cold storage using Custodiol® (Histidine-Tryptophan-Ketoglutarate, HTK) or isotonic saline solution on mitochondrial function in hearts (left and rights ventricles) and various blood vessels of pigs were investigated. Hearts, saphenous veins, internal-mammary-arteries and aortas of male landrace pigs were harvested and exposed to cold ischemia in either saline or Custodiol-HTK solution. Mitochondrial function was measured in situ in permeabilized fibers by high-resolution respirometry. Mitochondrial respiratory capacities (maximal respiration rates) were similar in the right and left ventricle in controls and after 14 h of cold storage were significantly better preserved in Custodiol-HTK than in saline solution. Mitochondrial respiration rates in various blood vessels including aorta, arteries and veins were less than 5% of myocardium rates. In contrast to the pig heart, in some blood vessels, like veins, mitochondrial function remained stable even after 24 h of cold ischemia. HTK

Respiration assays are routinely used for investigating microbial metabolic activity in soil, but usually after a period of conditioning whereby dry soil is rewetted and incubated for a period of days. We showed that rewetting and incubation of soil with or without amendments cause changes in microbial populations that are dependent on the type of amendment. As these amendments resulted in altered basal respiration levels and SIR profiles, they call into question the suitability of soil conditioning as pretreatment for soil microbial analyses. When testing soils from an experiment involving various amendments we have found that different substances can inhibit, rather than stimulate, respiration following rewetting. We suggest further investigation of CO2 burst inhibition for the purpose of developing a method that does not require naturally dry or air dried soil to undergo conditioning prior to a SIR assay.. ...

AU - Widener, Linda L.. AU - Bartos, Dagmar. PY - 1990/4. Y1 - 1990/4. N2 - Mitochondrial pyruvate‐supported respiration was studied in vitro under conditions known to exist following ischemia, i.e., elevated extramitochondrial Ca2+, Na+, and peroxide. Ca2+ alone (7-10 nmol/mg) decreased state 3 and increased state 4 respiration to 81 and 141% of control values, respectively. Sodium (15 mM) and/or tert‐butyl hydroperoxide (tBOOH; up to 2,000 nmol/mg protein) alone had no effect on respiration; however, Na+ or tBOOH in combination with Ca2+ dramatically altered respiration. Respiratory inhibition induced by Ca2+ and tBOOH does not involve pyruvate dehydrogenase (PDH) inhibition since PDH flux increased linearly with tBOOH concentration (R= 0.96). Calcium potentiated tBOOH‐induced mitochondrial NAD(P)H ...
Studying whole cell preparations with intact mitochondria and respiratory complexes has a clear benefit compared to isolated or disrupted mitochondria due to the dynamic interplay between mitochondria and other cellular compartments. Platelet mitochondria have a potential to serve as a source of human viable mitochondria when studying mitochondrial physiology and pathogenic mechanisms, as well as for the diagnostics of mitochondrial diseases. The objective of the present study was to perform a detailed evaluation of platelet mitochondrial respiration using high-resolution respirometry. Further, we aimed to explore the limits of sample size and the impact of storage as well as to establish a wide range of reference data from different pediatric and adult cohorts. Our results indicate that platelet mitochondria are well suited for ex-vivo analysis with the need for minute sample amounts and excellent reproducibility and stability ...

He has found that the standard American diet is highly deficient in certain parent oils, which are needed in small amounts to build healthy cells and to provide for proper cell respiration. The absence of healthy oils damages cellular respiration and contributes to cancer formation. He has developed a blend of oils, which provide what the body needs to provide for proper cellular respiration. Also, most Americans are deficient in certain minerals. He uses supplements to provide for these deficiencies. Finally he uses a combination of herbs that are similar to Essiac Tea (described later) to assist with cleansing and detoxification of the body.

Thus, respiration defines the chemical reaction which includes the breakdown of the nutrient molecule to produce energy. Moreover, it exists in the mitochondria or the cytoplasm of the cell in an aerobic manner or anaerobic manner.. Types of Respiration. There are two different types of respiration. They are:. Aerobic Respiration. Anaerobic Respiration. Definition of Aerobic Respiration. The process of reactions catalyzed by enzymes is called aerobic respiration. Also, this mechanism comprises the transfer of electrons from the molecules that perform as the source of fuel like glucose to oxygen. Further, it works as the final electron acceptor.. Definition of Anaerobic Respiration. The main difference between aerobic and anaerobic respiration refers to the involvement of oxygen when the provided resources like glucose are recycled into energy. Also, this system has been developed by some bacteria in which it generates use of oxygen-containing salts rather than free oxygen as the electron ...
PMID: 28588260 Sci Rep Open Access Lemieux H, Blier PU, Gnaiger E (2017) Sci Rep Abstract: Fuel substrate supply and oxidative phosphorylation are key determinants of muscle performance. Numerous studies of mammalian mitochondria are carried out (i) with substrate supply that limits electron flow, and (ii) far below physiological temperature. To analyze potentially implicated biases, we studied mitochondrial respiratory control in permeabilized mouse myocardial fibers using high-resolution respirometry. The capacity of oxidative phosphorylation at 37 °C was nearly two-fold higher when fueled by physiological substrate combinations reconstituting tricarboxylic acid cycle function, compared with electron flow measured separately through NADH to Complex I or succinate to Complex II. The relative contribution of the NADH pathway to physiological respiratory capacity increased with a decrease in temperature from 37 to 25 ºC. The apparent excess capacity of cytochrome c oxidase above physiological ...

In the mitochondria, there is a chain of electron carriers, which is best known as the electron transport chain. It is through this chain that electrons from the oxidative reactions before pass along the chain. NADH donates two electrons to the first carrier in the chain. Then, these two electrons go along the chain releasing energy from one carrier to the next. At the third location of the chain, enough energy has been released to produce ATP with the usage of the ATP synthase, which is an enzyme that is found in the inner mitochondrial membrane as well. FADH2 donates electrons but at later stage than NADH. Enough energy is released at only two locations of the chain by electrons from FADH2. The ATP production relies on the released energy by oxidation and it is thus called oxidative ...

Respiration affects the cardiovascular system significantly and this is observed in hemodynamic parameters such as stroke volume and heart rate. The morphology of signals relevant to the heart also changes with respiration. Such changes have been used to extract respiration signal from the electrocardiogram (ECG). It is also shown that accelerometers placed on the body can be used to extract respiration signals. Apart from measuring the respiration rate or estimating the respiration signal morphology, what is also important is to detect the phases of respiration using the same accelerometers. This project mainly focuses on detection of the start and end timings of respiration phases and also discriminating heart beats related to inhaling from those related to exhale phases rather than detecting them alone or computing respiration rates only. Thus, the idea behind this study is to compare the efficacy of accelerometer-derived respiration (ADR) to Electrocardiogram derived respiratory (EDR) in ...

These oxygen sensors showed good repeatability during 6 consecutive measurements at 300-s intervals, with an output of 108.2 ± 3.15 nA (mean ± standard deviation) for the air-saturated state and 1.33 ± 0.14 nA for the zerooxygen state. In addition, these sensors showed good linearity, with a correlation coefficient of 0.995 and a sensitivity averaging 2.04 A/cm2 M. A LabVIEW-based measurement system was developed for simultaneously measuring the multiple cellular ...

Video explaining Cellular Respiration for Biology. This is one of many videos provided by Clutch Prep to prepare you to succeed in your college classes.
Cellular respiration is an exothermic reaction that takes place in all living cells and supplies all the energy needed for living processes. Respiration in cells can take place in the presence of oxygen, aerobically or in the absence of oxygen, anaerobically. Organisms need energy for chemical reactions to build larger molecules, for movement and to maintain a constant internal environment and temperature. All living cells respire including plants. Plants use the glucose they produce to make energy for their cells in order to support growth.. Aerobic respiration is the primary type of respiration that takes place inside animal cells. Aerobic respiration coverts glucose and oxygen into carbon dioxide and water. The reaction for aerobic respiration is the reverse of the reaction for photosynthesis so if you know one, you know the other.. ...

... live in all of the oceans, particularly in tropical and warm subtropical waters. They are commonly found in the epipelagic zone, the top layer of the ocean to a depth of about 200 m (656 ft). Numerous morphological features give flying fish the ability to leap above the surface of the ocean. One such feature is fully broadened neural arches, which act as insertion sites for connective tissues and ligaments in a fish's skeleton. Fully broadened neural arches act as more stable and sturdier sites for these connections, creating a strong link between the vertebral column and cranium.[10] This ultimately allows a rigid and sturdy vertebral column (body) that is beneficial in flight. Having a rigid body during glided flight gives the flying fish aerodynamic advantages, increasing its speed and improving its aim.[10] Furthermore, flying fish have developed vertebral columns and ossified caudal complexes.[11] These features provide the majority of strength to the flying fish, allowing them ...
