WebThe citric acid cycle can be regulated in one of several different ways. We can regulate it indirectly by controlling pyruvate decarboxylation (which is the process that occurs before the citric acid cycle begins) or we can regulate it directly by controlling a few of the steps involved directly in the citric acid cycle. WebIn the mitochondria, acetyl CoA continues on to the citric acid cycle. The citric acid cycle (CAC or TCA- tricarboxylic acid cycle) is also known as the Krebs cycle. During the conversion of pyruvate into the acetyl group, a molecule of CO 2 and two high-energy electrons are removed.
