Quizplus · Accepted Answer

Cytochrome oxidase (CO) is the key regulatory enzyme of the electron transport chain. It is responsible for the final step of oxidative phosphorylation, which involves the transfer of electrons to oxygen to form water. CO is regulated by the concentration of oxygen and the proton gradient, and its activity is closely linked to ATP synthesis. Therefore, changes in CO activity have a direct impact on the rate of electron transport and ATP production.
