Question
What happens when the proton gradient is disrupted in mitochondria?
Correct Answer
Option B is the correct answer.
Detailed Explanation
The proton gradient (proton motive force) is the direct energy source for ATP synthase. If the gradient is disrupted (e.g., by uncouplers or membrane damage), protons flow freely, and ATP synthesis grinds to a halt.
Hint
No gradient means no power for the ATP-making turbine.
