Which of the following statements is true? A. The NADH dehydrogenase complex can pump more protons than can the cytochrome b-c1 complex. B. The pH in the mitochondrial matrix is higher than the pH in the intermembrane space. C. The proton concentration gradient and the membrane potential across the inner mitochondrial membrane tend to work against each other in driving protons from the intermembrane space into the matrix.
