Now, one way by which the cells can actually regulate this pathway is by regulating the enzyme that catalyzes this step. So remember, Pyruvate decryptoxylation is regulated by an enzyme complex known as Pyruvate dehydrogenase complex. And this actually consists of three different types of proteins, three different types of enzymes. 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.
