So we ultimately see there are two types of inhibitors and two types of activators. So we have ATP molecules and citrate molecules that inhibit the phosphor fructokinase. But the amp molecules and the fructose 26 bisphosphate are actually activators of the fructose of the phosphor fructokinase enzyme. So once again, when fructose six phosphate concentration is high, some of it is transformed into fructose 206 bisphosphate. And this molecule is an allosteric activator of the enzyme. It binds to that enzyme, stimulates its activity and it continually carries out this process quickly and effectively.
