Question

The maintenance of proton motive force requires that inner mitochondrial membrane remains permeable to protons.

(a) True

(b) False

This question was posed to me in homework.

Question is from Aerobic Respiration topic in division Nucleus & Aerobic Respiration of Cell Biology

Answer 1

The correct answer is (b) False

The explanation: The inner mitochondrial membrane must remain highly impermeable to protons otherwise the gradient established by electron transport would be quickly dissipated by the leakage of protons back into the matrix.
