Adenosine receptor: The adenosine receptors (or P1 receptors) are a class of purinergic G protein-coupled receptors with adenosine as endogenous ligand.Inhibitor protein: The inhibitor protein (IP) is situated in the mitochondrial matrix and protects the cell against rapid ATP hydrolysis during momentary ischaemia. In oxygen absence, the pH of the matrix drops.Adenosine deaminase deficiencyBAY 60–6583Energy charge: Energy charge is an index used to measure the energy status of biological cells.

Two isoenzymes are found in commercial preparations from S.TheophyllineSodium hexametaphosphateBurst kinetics: Burst kinetics is a form of enzyme kinetics that refers to an initial high velocity of enzymatic turnover when adding enzyme to substrate. This initial period of high velocity product formation is referred to as the "Burst Phase".Magnesium acetateNTP binding site: An NTP binding site is a type of binding site found in nucleoside monophosphate (NMP) kinases, N can be adenosine or guanosine. A P-loop is one of the structural motifs common for nucleoside triphosphate (NTP) binding sites, it interacts with the bound nucleotide's phosphoryl groups.Uridine triphosphatePhosphocreatineSurE, survival protein E: In molecular biology, the protein domain surE refers to survival protein E. It was originally found that cells that did not contain this protein, could not survive in the stationary phase, at above normal temperatures, and in high-salt media.Calcium signaling: Calcium ions are important for cellular signalling, as once they enter the cytosol of the cytoplasm they exert allosteric regulatory effects on many enzymes and proteins. Calcium can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.Crosstalk (biology): Biological crosstalk refers to instances in which one or more components of one signal transduction pathway affects another. This can be achieved through a number of ways with the most common form being crosstalk between proteins of signalling cascades.Index of energy articles: This is an index of energy articles.Adenosine thiamine triphosphateThiotrisescaline: T-TRIS, or thiotrisescaline, is a series of lesser-known psychedelic drugs similar in structure to trisescaline. They were first synthesized by Alexander Shulgin and written up in his book PiHKAL (Phenethylamines i Have Known And Loved).P/O ratio: The Phosphate/Oxygen Ratio, or P/O Ratio, refers to the amount of ATP produced from the movement of two electrons through a defined electron transport chain, donated by reduction of an oxygen atom.Garrett & Grisham 2010, p.TRNA (adenine57-N1/adenine58-N1)-methyltransferase: TRNA (adenine57-N1/adenine58-N1)-methyltransferase (, TrmI, PabTrmI, AqTrmI, MtTrmI) is an enzyme with system name S-adenosyl-L-methionine:tRNA (adenine57/adenine58-N1)-methyltransferase. This enzyme catalyses the following chemical reactionNucleoside analogue: Nucleoside analogues are nucleosides which contain a nucleic acid analogue and a sugar. Nucleotide analogs are nucleotides which contain a nucleic acid analogue, a sugar and one to three phosphate groups.Alkaliphile: Alkaliphiles are a class of extremophilic microbes capable of survival in alkaline (pH roughly 8.5-11) environments, growing optimally around a pH of 10.New Zealand rabbitDipyridamoleConcentration effect: In the study of inhaled anesthetics, the concentration effect is the increase in the rate that the Fa(alveolar concentration)/Fi(inspired concentration) ratio rises as the alveolar concentration of that gas is increased. In simple terms, the higher the concentration of gas administered, the faster the alveolar concentration of that gas approaches the inspired concentration.Myocytolysis: Myocytolysis refers to a degenerative change (often reversible) that occurs to myocytes upon myocardial strain. This phenomenon tends to occur when neighboring cardiac muscle loses its ability to contract (i.Tetrasodium pyrophosphateMizoribineDeoxyadenosine triphosphate: = = =PurineSmoke DZA: New York, New York, United StatesNucleotide Pyrophosphatase/Phosphodiesterase (NPP): Nucleotide pyrophosphatase/phosphodiesterase (NPP) is a class of dimeric enzymes that catalyze the hydrolysis of phosphate diester bonds. NPP belongs to the alkaline phosphatase (AP) superfamily of enzymes.Spin–lattice relaxation in the rotating frame: Spin–lattice relaxation in the rotating frame is the mechanism by which Mxy, the transverse component of the magnetization vector, exponentially decays towards its equilibrium value of zero, under the influence of a radio frequency (RF) field in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). It is characterized by the spin–lattice relaxation time constant in the rotating frame, T1ρ.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingAnaerobic glycolysis: Anaerobic glycolysis is the transformation of glucose to pyruvate when limited amounts of oxygen (O2) are available. Anaerobic glycolysis is only an effective means of energy production during short, intense exercise, providing energy for a period ranging from 10 seconds to 2 minutes.Trans-tubular potassium gradient: The trans-tubular potassium gradient (TTKG) is an index reflecting the conservation of potassium in the cortical collecting ducts (CCD) of the kidneys. It is useful in diagnosing the causes of hyperkalemia or hypokalemia.Phosphotransferase: Phosphotransferases are a category of enzymes (EC number 2.7) that catalyze phosphorylation reactions.Steptoean positive carbon isotope excursion: The Steptoean Positive Carbon Isotope Excursion (SPICE) was a geological event which occurred about 500 million years ago at the end of the Cambrian Period. The SPICE event was a sudden reversal of the anoxia (lack of oxygen) that had steadily spread throughout the oceans during the Cambrian which also affected the atmosphere.Isocyanide: An isocyanide (also called isonitrile or carbylamine) is an organic compound with the functional group -N≡C. It is the isomer of the related cyanide (-C≡N), hence the prefix iso.A. N. Hartley: Annie Norah Hartley (1902 – 1994), usually known simply as Norah Hartley, was a dog breeder and the first female board member of the Kennel Club.Erythrocrine: Erythrocrine describes red blood cell or erythrocyte for production and release of signaling molecules. The term “erythrocrine“ was coined by Song et al.Respirometer: A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. They allow investigation into how factors such as age, chemicals or the effect of light affect the rate of respiration.LuciferinDNA binding site: DNA binding sites are a type of binding site found in DNA where other molecules may bind.
