Assume that you have a cell that is able to complete glycolysis, the citric acid cycle, and the steps of oxidative phosphorylation involving the electron transport chain. However, the ATP synthase in this cell allows passage of H+ ions but does not produce ATP. When grown in aerobic conditions, you expect this cell to generate

A: The same amount of ATP as a cell that was fermenting.
B: A little more ATP than a cell that was fermenting.
C: A little less ATP than a cell that was fermenting.
D: About the same amount of ATP as a cell that was respiring normally under aerobic conditions

The answer is: B
