Solution
Verified by Toppr
The correct option is D A and B both Cyclic photophosphorylation provides energy for the calvin cycle and involves only p680 in photosystem ll. Non-cyclic photophosphorylation involves p700 in photosystem l and p680 in photosystem ll. Cyclic photophosphorylation produces ATP. Non-cyclic photophosphorylation produces NADPH by reducing NADP and ATP. Oxygen is released during non-cyclic photophosphorylation.
Thus, the correct answer is 'A and B both.'
