The inner mitochondrial membrane normally _____.
A)contains permease channels that allow small ions and water to pass readily through the membrane by simple diffusion
B)contains an active transport pump that pumps protons into the inner mitochondrial compartment from the point of high concentration to a point of lower concentration
C)is virtually impermeable to hydrogen ions (protons)
D)contains enzymes responsible for two of the chemical reactions that take place as part of glycolysis

Question

Quizplus · Accepted Answer

The inner mitochondrial membrane is virtually impermeable to hydrogen ions (protons), which is crucial for maintaining the proton gradient used in ATP synthesis during oxidative phosphorylation.
