Now, notice because the reaction took place on the beta carbon of the fatty acid and this was an oxidation reaction, we call this particular pathway the beta oxidation pathway. So this series of four reactions that basically takes place over and over and over until that fully saturated fatty acid is completely converted into these acetyl coenzyme A molecules, is known as the beta oxidation pathway. So once we actually generate those acetyl coenzyme A molecules, they are then fed into the citric acid cycle. And in the next lecture, we're going to discuss how many ATP molecules are actually formed in this process. So when this entire four step process actually takes place one time, we generate a single fadh two molecule and a single NADH molecule. And these can then go on the electron transport chain to help generate ATP molecules, as we'll discuss in the next lecture.
