Light-dependent electron flow with the production of ATP can occur without the formation of NADPH.Which of the following photosystems is involved in this cyclic photophosphorylation?
A)P700
B)photosystem II
C)P680
D)ferredoxin

Question

Quizplus · Accepted Answer

Cyclic photophosphorylation involves the recycling of electrons back to the electron transport chain from photosystem I (P700) without passing through photosystem II (P680). This leads to the production of ATP without the formation of NADPH.
