Let's look at step three. So the point of step three is to continue destabilizing that molecule. So in step one we destabilized it, increased its energy and made it more reactive because we made it more polar, we added a charge and here we add a second charge and that makes it even more reactive and more likely to actually undergo cleavage in stage two. So we take the fructose six phosphate and again, because we want to add a pisphory root, what type of enzyme are we going to have? Well, a kinase. What type of kinase?
