Which of the following is true regarding proton movement in the mitochondria?

Question

Quizplus · Accepted Answer

2,4-dinitrophenol is a mitochondrial uncoupler that disrupts the electrochemical gradient, allowing protons to move back into the matrix without generating ATP. Option A is incorrect because complex III pumps 4 protons across the inner membrane, not 2. Option B is incorrect because protons actually move from the intermembrane space to the matrix via the ATP synthase, not the other way around. Option D is incorrect because it is the intermembrane space that becomes acidic due to proton movement.
