Question

In photosynthesis, photolysis of water is used in
(a) Reduction of NADP
(b) Oxidation of NADP
(e) Oxidation of FAD
(d) None of the above

Answer 1

The answer should be d because the electron that dissociates from H2O is taken by PS2 and the electron that reaches NADP reductase is of PS1 not of PS2

Answer 2

In photosynthesis, photolysis of water is used in

Answer: (d) None of the above

Explanation:  

Photosynthesis is the process where the green plants using light energy to convert it to food. Photolysis of water takes place in PS1. Whereas the production of nutrients takes place in PS2. NADP and FAD2 are oxidised in the PS2 phase of photosynthesis.  

There is actually no relationship between photolysis of water to form Hydrogen ion and oxygen with that of reduction of nutrients. So the best answer of here is none of the above.
