So we have the C, four keto acyl coenzyme A. Now, if this molecule undergoes one more beta oxidation, then we produce these two identical acetylcoenzine A molecules. And so that's why we need six plus one more. So seven cycles of beta oxidation to produce a total of six, seven and eight acetyl coenzyme A molecules. Now, acetylco enzyme A molecules are not the only energy bearing molecules that are produced within the beta oxidation process. We also generate one NADH molecule and one Fadh, two molecule every time the beta oxidation process actually takes place.
