So we see that these two steps and this step are different than the steps in Glycolysis, but these steps are exactly the same. Now, once we form the fructose six phosphate, then we follow the same exact step as in Glycolysis, except in reverse. Why? Well, for the same exact reason that we mentioned here. Essentially these two molecules in Glycolysis are at equilibrium, and that means their free energy value is very, very close to zero. And so they're at equilibrium and we can basically use the same exact type of enzyme, phosphor, glucose isomerase, to transform the fructose six phosphate into the glucose six phosphate.
