"La phosphorylation oxydative fait intervenir des réactions qui libèrent de l'énergie pour réaliser des réactions qui consomment de l'énergie : on dit que ces deux groupes de réactions sont couplées. Cela signifie que les unes ne peuvent se produire sans les autres. La circulation des électrons à travers une chaîne de transport d'électrons — de la chaîne respiratoire ou de la photosynthèse — est un processus exergonique, c'est-à-dire qu'elle libère de l'énergie ; la biosynthèse de l'ATP par l'ATP … " - Phosphorylation oxydative schéma
