Two groups of cells were grown under identical conditions. Mitochondria from each group were isolated and half of them were placed in a low pH (approximately pH 6.8) and the other half were placed in a neutral pH. Small molecules were allowed to diffuse across the outer membrane via facilitated diffusion. Both samples were exposed to oxygen bubbles through the growth media. What would you expect to see in terms of ATP production in the sample of cells placed in a low pH, with respect to the control population?
(A) ATP production decreases.
(B) ATP production increases.
(C) ATP production stays the same.
(D) ATP production ceases entirely.
