And finally, let's move on to the Pyruvate kinase. So pyruvate kinase is the enzyme that catalyzes the last process in glycolysis and this is also virtually irreversible. It only takes place in this direction. So we have phosphorinopyruvate that is transformed into pyruvate molecules and ATP molecules by the activity of pyruvate kinase. Now just like phosphor, fructokinase is inhibited by ATP molecules. So it's pyruvate kinase.
