And this step essentially releases energy and this is a step that drives this entire step one of the citric acid cycle. So once again, the first step produces a citro coenzyme A complex which contains the six carbon component attached onto the coenzyme A. This reaction is what we call an Aldo condensation. The second step releases the coenzyme a component to form the citrate molecule as well as this individual coenzyme A. And this is a hydrolysis reaction which we use a water to actually cleave this bond. And so the oxygen essentially attaches itself onto this carbon here to form this group shown here.
