  • 2007). In chlorophototrophs, light energy is transduced into chemical potential energy by reaction centers, photo-oxidoreductases that form two families of BChl/Chl-containing, pigment-protein complexes ( Golbeck, 1993 ). (tcdb.org)
  • This work has revealed the pathways, rates, and yields of the electron transfer reactions but has also raised several intriguing questions about how these properties are governed by the protein-cofactor interactions. (schoolbag.info)
  • PSII
  • PSII, inter-chain carriers, PSI), and potentially provide some insights into alternate electron flow. (carnegiescience.edu)
  • CO2 fixation is saturated but qP stays high) would suggest the existence of alternative pathways for extracting electrons from PSII, which would include the Mehler reaction (an electron leak on the reducing side of PSI, probably from the ferredoxin-NADP oxidoreductase, and the generation of H2O2) or potentially the re-reduction of O2 and H+ to regenerate H2O through a plastid terminal oxidase (PTOX).

  • This technology allows for the application of single or multiple turnover subsaturating excitation pulses at microsecond intervals to induce fluorescence transients, allowing measurements of the photochemical conversion efficiency in PSII (Fv/Fm), the functional absorption cross section of PSII (σPSII) and the energy transfer between PSII units (p).

  • NADH
  • Comparative structures of two related electron carriers: NADH and NADPH. (csbsju.edu)
  • Because NADH and NADPH are electron carriers, it is important to recognise both reduced and oxidised forms. (csbsju.edu)
  • The problem is, NADPH is a relatively high-energy electron carrier -- remember, NADH was at the uphill end of the electron transport chain in oxidative phosphorylation -- and our electrons have just ridden their sled to the bottom of the hill. (csbsju.edu)

  • The crucial role in preventing the generation of reactive oxygen species belongs to dynamic regulation of electron transport activity despite the presence of complex system of their detoxification in chloroplasts. (springer.com)
