Evidence for chemiosmotic coupling as the mechanism for oxidative phosphorylation is based on the observation that
A) mitochondrial membrane fragments without compartmentalization can carry out oxidative phosphorylation
B) submitochondrial preparations that contain closed vesicles can carry out oxidative phosphorylation
C) many different kinds of substances can serve as uncouplers
D) it has proved impossible to duplicate the process in model systems

Question

Quizplus · Accepted Answer

Submitochondrial preparations that contain closed vesicles can carry out oxidative phosphorylation, demonstrating the importance of compartmentalization for the chemiosmotic mechanism, where a proton gradient across the membrane drives ATP synthesis.
