In a mitochondrion, if the matrix ATP concentration is high and the intermembrane space proton concentration is too low to generate sufficient proton-motive force, then
A) ATP synthase will increase the rate of ATP synthesis.
B) ATP synthase will synthesize ATP and pump protons into the intermembrane space.
C) ATP synthase will hydrolyze ATP and pump protons into the intermembrane space.
D) ATP synthase will hydrolyze ATP and pump protons into the matrix.
E) ATP synthase will synthesize ATP and pump protons into the matrix.

Question

Quizplus · Accepted Answer

ATP synthase can work in reverse, hydrolyzing ATP to pump protons into the intermembrane space when the proton-motive force is insufficient for ATP synthesis.
