Answer
The switch to aerobic metabolism allows ATP to be produced by oxidative phosphorylation. The phosphorylation of ADP increases the [ATP]/[ADP] ratio, which then increases the [NADH]/[NAD] ratio because a high ATP mass action ratio slows electron transport. The increases in [ATP] and [NADH] inhibit their target enzymes in glycolysis and the citric acid cycle and thereby slow these processes.
