Question

Non-cyclic photophosphorylation is performed by

• A. Dark reaction
• B. PS I
• C. PS II
• D. Both B and C

Answer 1

The correct option is D Both B and C

Non-cyclic photophosphorylation involves both PS I and PS II and the flow of electron is unidirectional as they are not cycled back but used in the reduction of NADP into NADPH. Here water is utilized to give electrons and oxygen is evolved.

So, the correct option is 'Both B and C'.
