We have e one, e two and E three. Now, E One is also known as Pyruvate dehydrogenase, e Two is also known as dihydrolypoil acetyl, trans acetylase, and E Three is known as Dihydrolypoil dehydrogenase. And these three enzymes are found within this complex and they catalyze different steps of Pyruvate degreeboxylation. Now, let's suppose in our cell we have plenty of ATP molecules. And if we have plenty of ATP molecules, that basically means we're going to have plenty of intermediate molecules that are used to actually produce those ATPs. So we're going to have high levels of NADH and acetylcoenzyme A.
