Now, the citric acid cycle is basically a series of eight steps, a series of eight reactions, as shown in the following diagram. We have 123-4567 and eight. Now, the entire purpose of the citric acid cycle is to basically take the energy that is stored within our acetyl coenzyme A and transfer that energy in the form of high energy electrons to our electron carrying molecules, our NADH and Fadh, too. So the citric acid cycle doesn't actually directly form ATP molecules. What it actually does is it forms these NADH and fadh two molecules, the high energy electron carriers that will then be used by the electron transport chain to synthesize the ATP molecules. Now, the way that we described our citric acid cycle on the diagram is for a single acetyl coenzyme A.
