Q. Which one of the following is not true regarding the release of energy during ATP synthesis through chemiosmosis? It involves:
A) Reduction of NADP to $NADPH_2$ on the stroma side of the membrane
B) Breakdown of proton gradient
C) Breakdown of electron gradient
D) Movement of protons across the membrane to the stroma
Explanation
[Solution] ATP is synthesised when the proton gradient breaks down as $H^+$ move through $CF_0$ into the stroma; there is no 'electron gradient' involved. Answer (3).
