1) why one reductant to other reductant? Imagine H2 + Na+ -> hydrogen is reductant, rigth? Na+ is in oxidised form, rigth? 2) I don't think it's kind of connected with the TCA cycle, because NADH2 is re-oxidized in the electron ...

Biochemistry

I have two true and false questions: 1) Electron from the reductant of a redox couple can transfer exergonically to the oxidized member of another couple that has a more positive standard reduction potential. What I think: At first I thought it is true, ...

water oxidizing clock in light reaction of photosynthesis

... and for NADPH production. PS1 is very good at transferring an electron, whether it be to NADP or to ferredoxin (fd). It is a powerful reductant. PS2, on the other hand, is better at grabbing electrons from water to transfer them to quinone (Q). It is a good oxidant. I think it might ...

ESSENTIAL COMPONENT OF PHOTOSYNTHESIS-CHLOROPHYLL

... setting up a chemiosmotic potential mainly used to produce ATP chemical energy, and those electrons ultimately reduce NAD+ to NADPH a universal reductant used to reduce CO2 into sugars as well as for other biosynthetic reductions. Reaction center chlorophyll-protein complexes are capable of ...

... from water. The cyanobacterial pathway in Arthrospira maxima uses a dark fermentative pathway to produce H2 from photosynthetically generated reductant, thereby achieving temporal separation of O2 production, a requirement for practical applications in energy generation. :shock: ___________________________ ...
