What is the primary function of cyclic electron flow?
A)to produce additional NADPH
B)to produce additional ATP
C)to produce additional oxygen
D)to produce additional carbon dioxide

Question

Quizplus · Accepted Answer

The primary function of cyclic electron flow is to produce additional ATP by cyclic photophosphorylation. The electron transport chain between photosystem I and cytochrome b6f complex pumps protons across the thylakoid membrane, creating a proton gradient for ATP synthesis by ATP synthase. This process produces ATP without producing NADPH or releasing oxygen. Therefore, choice A and C are incorrect, and choice D is unrelated to cyclic electron flow.
