That's why we call this the investment stage. Now stage two we call the cleavage state because this is where we break down this molecule that we form in stage one. So we take the fructose one six bisphosphates and under the guidance of an enzyme called aldolase. Why? Aldalase well because this is an aldol reaction and in fact going backwards is an aldol condensation. And so that's why we call this an aldolase.
