Question

H2 donor during photosynthesis is

Answer 1

Answer:

NADPH is answer

Explanation:

NADPH is the H2o donor during the process of photosynthesis. NADPH is the reduced form of NADP  +.

In photosynthetic organisms, NADPH is produced by ferredoxin NADP  

+

 reductase in the last step of the electron chain of the light reactions of photosynthesis.

It is used as reducing power for the biosynthetic reactions in the Calvin cycle to assimilate carbon dioxide. It is used to help turn the carbon dioxide into glucose.

Answer 2

Answer:

Plants and one type of bacteria (cyanobacteria) do produce oxygen, an evolutionarily more advanced type of photosynthesis (in which the hydrogen donor is water). In a broad chemical sense, the opposite of photosynthesis is respiration.
