And what this produces is acetocoenzyme A. Now, once this step takes place, it's an irreversible step that commits the glucose derivative, the CETO coenzyme A to undergoing the citric acid cycle. Or in some cases, we can actually use it to form fat molecules, as we'll discuss in a future electron. But basically, by regulating this step, we call pyruvate carboxylation. By either turning it on or off, we can regulate the rate of the citric acid cycle. Now, that's the first process of regulation.
