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. And as we increase the concentration of glucose six phosphate due to the inhibition of PFK, that increase in concentration will inhibit the hexokinase. And this same exact regulatory mode is actually used by skeleton muscles as well. So just as in skeleton muscle cells, glucosex phosphate is also an allosteric inhibitor to hexokinase.
