In a plant cell undergoing respiration, how does the proton gradient across the inner mitochondrial membrane contribute to ATP synthesis?

Protons flow through ATP synthase, driving the synthesis of ATP.

Protons are used to generate NADH, which is a precursor for ATP synthesis.

Protons combine with oxygen to form water, releasing ATP as a byproduct.

Protons inhibit the activity of ATP synthase, promoting ATP synthesis.

Text Solution

Verified by Experts

The correct answer is:

NOT AVAILABLE

Protons flow through ATP synthase, driving the synthesis of ATP. The proton gradient across the inner mitochondrial membrane is utilized by ATP synthase to generate ATP through the process of chemiosmosis.
