And so there will be a build up in the concentration of fructose six phosphates in our cell. Now fructose six phosphate is in equilibrium with glucose six phosphate and biliciously as principle. If we increase the concentration of this product, we're going to increase the concentration of this reactant as well. So the increase in concentration of this increases the concentration of the glucose six phosphate. And when that takes place, the rise in the concentration of glucosex phosphate causes a negative feedback loop with the hexokinase. And so it goes on and binds up to hexokinase and that causes hexokinase to basically inhibit its activity.
