Now, once phosphorkinase is inhibited, so this molecule is basically inhibited PFK is phosphorinase, then we're going to see that there is a build up of this substrate molecule that is a substrate to this enzyme fructose six phosphates. So by the way, this is step one of glycolysis, step two of glycolysis and step three of glycolysis. And once there is a build up of this molecule, because of the inhibition of this molecule by the ATP, this molecule is in equilibrium with this molecule. And so if we increase the concentration of this, if there's a build up of this bilaterally as principle, it will shift this way and increase the concentration of glucose six phosphate. Now glucose six phosphate is the product molecule to this reaction. So glucose is transformed by hexagonase in the first step of glycolysis to form glucose six phosphate.
