In the two light reactions of photosynthesis

A

PS I produces strong oxidant while PS II a strong reductant

B

PS I produces strong reductant NADPH while PS II a strong oxidant

C

PS I emits electrons for PS II

D

PS I produces ATP which is not fonned by PS II

Text Solution

Verified by Experts

The correct Answer is:
B
In the two light reactions of photosynthesis, PS I produces strong reductant NADPH while PS II a strong oxidant `(O_(2))`.
