If you added a protonophore (a substance that makes membranes leaky for protons) to mitochondria, what would happen to the amount of ATP produced? a) More ATP because a leaky inner membrane will allow more protons to diffuse across the membrane. b) More ATP because a leaky outer membrane will allow more protons to diffuse across the membrane. c) Less ATP since protons must accumulate in the inner membrane space in order to produce ATP. d) Less ATP since electrons must accumulate in the inner membrane space in order to produce ATP. e) No change in ATP production would occur

As electrons move from Complex I & II to Complex IV, H+ ions accumulate in the intermembrane space. Describe how these ions are then used to generate ATP using the following terms: ATP synthase, ADP, ATP, electrochemical gradient, chemiosmosis, intermembrane space, matrix.
Imagine that you develop a procedure to measure the pH of in the matrix and the intermembrane space of a mitochondrion. What pattern of pH would you see? The pH in the intermembrane space will contain more H+ and have a lower pH compared to the matrix. The pH in the intermembrane space will contain more H+ and have a higher pH compared to the matrix. The pH within the matrix will contain more H+ and have a lower pH compared to the intermembrane space. The pH within the matrix will contain more H+ and have a higher pH compared to the intermembrane space.
