Or under other conditions, the CETO cola enzyme A can be committed to a second pathway that produces lipids. And we'll talk more about that in a future lecture. So we see that the Pyruvate decarboxylation process is a very important step, very crucial step in glucose metabolism because it essentially commits that glucose derivative molecule, the Pyruvate, into carrying out the citric acid cycle or in some cases, lipid synthesis. 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.
