And so this requires succinct coenzyme a. So you form succinate and acetoacetal coenzyme A. And then this acetyl coenzyme A reacts with a coenzyme a molecule and is catalyzed by thylase to form two acetyl coenzyme a molecules, which then can be used to generate these energy molecules. So we see that ketone bodies inside a target cell can be broken down into acetyl coenzyme a molecules. Now, we see that if we use d three hydroxybutyrate, then not only will we ultimately generate the acetyl coenzyme A, we will also generate NADH inside a target cell. And so the NADH can actually be used by the electron transport chain to generate those ATP molecules.
