The rate of oxidative phosphorylation
(I) is regulated by the availability of ADP and P_i.
(II) is reduced when the ratio of [NADH]/[NAD⁺] is high.
(III) increases with a higher concentration of reduced cytochrome c
(IV) is regulated by activity of the ADP-ATP translocator.

Question

Quizplus · Accepted Answer

I is true, as the rate of oxidative phosphorylation is regulated by the availability of ADP and Pi.
II is also true, as the rate of oxidative phosphorylation reduces when the ratio of [NADH]/[NAD+] and [NADPH]/[NADP+] is high.
III is true, as the rate of oxidative phosphorylation increases with a higher concentration of reduced cytochrome c.
IV is true, as the rate of oxidative phosphorylation is regulated by activity of the ADP-ATP translocator.
