So each time our acyl coenzyme A is shortened by two carbons, we basically produce a single NADH molecule, a single fadh two molecule, as well as an acetylco or an acetyl coenzyme A. So remember, an acyl coenzyme A and an acetyl coenzyme A are two different molecules. So we take the acyl coenzyme A, it undergoes beta oxidation in the matrix to produce our acetyl coenzyme A. And the acetyl coenzyme A is the fuel in the citric acid cycle. So it goes into the citric acid cycle to produce NADH and Sadh, two molecules which then end up on the electron transport chain to produce our ATP molecules. And this process of beta oxidation of shortening our acyl coenzyme A of the fatty acid continues until we no longer have any carbons left.
