Quizplus · Accepted Answer

The chemiosmotic mechanism occurs both in photosynthesis (in the light-dependent reactions) and respiration (in oxidative phosphorylation). It involves the generation of a proton gradient across a membrane, which drives ATP synthesis through ATP synthase. Therefore, both photosynthesis and respiration involve the synthesis of ATP by the chemiosmotic mechanism.
