And of course, we also regenerate the coenzyme A. And the coenzyme A can now be reused in the process of pyruvate carboxylation. Now, as we can see from the following overall reaction, step one of the citric acid cycle is actually a multi step process. It consists of two different steps. And both of these steps are essentially catalyzed by an enzyme known as citrate synthase. And as the name applies, as the name implies, we essentially synthesize the citrate molecule beginning with these two reactant molecules.
