And as we'll discuss in the next lecture, when we discuss how we regulate the process of Gluconeogenesis, this enzyme is actually used to regulate that process. So fructose one six bisphosphate is an allosteric enzyme that is also used in Gluconeogenesis regulation. And this enzyme catalyzes the exergonic hydrolysis of the established carbon one of fructose one six bisphosphate. 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?
