This process the cycle a second time because we have that second acetyl, coenzyme A. So the final three steps six, seven and eight of the citrix cycle involves the regeneration of our oxalo acetate molecule. The question is, how exactly does this take place? So, let's begin with our succinate. The succinate looks something like this. We have the carbon 1234, and these two H atoms shown in purple will basically react with a single fad molecule.
