We're going to have many ATP molecules what will that cause? Well, the ATP molecules will bind onto the regulatory sides of phosphorptokinase, inhibiting that molecule. And if this molecule is inhibited, the enzyme is inhibited, this fructosex phosphate cannot go on to the next molecule. 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.
