FAQs
Question: What is the main function of oxidative phosphorylation? Answer: The main function of oxidative phosphorylation is to produce ATP through the electron transport chain and chemiosmosis.
Question: How does oxidative phosphorylation differ from substrate-level phosphorylation? Answer: Oxidative phosphorylation generates ATP using energy from electrons transferred through the electron transport chain, while substrate-level phosphorylation directly transfers a phosphate group to ADP from a substrate.

Q. What is the effect of uncouplers on oxidative phosphorylation?
A.
Increase ATP production
B.
Decrease oxygen consumption
C.
Increase heat production
D.
Inhibit electron transport
Solution
Uncouplers disrupt the proton gradient, leading to increased heat production instead of ATP.
