The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that adenosine triphosphate (ATP) is formed because :-
Topic: NEET PYQ
Answer: A. Full step-by-step solution below.
- AA proton gradient forms across the inner membrane
- BThere is a change in the permeability of the inner mitochondrial membrane toward adenosine diphosphate (ADP)
- CHigh energy bonds are formed in mitochondrial proteins
- DADP is pumped out of the matrix into the intermembrane space
Correct answer: A
Solution
(a) Chemiosmotic theory states that ATP synthesis occurs due to the (proton) gradient across the inner mitochondrial membrane, which drives ATP synthase.More Respiration in Plants PYQs
