And now we have asymmetrical molecule. And once the cleavage takes place in stage two, that will ultimately allow us to produce two, three carbon molecules. And notice this stage one, because we're essentially investing to prepare that molecule for cleavage, we actually use energy molecules, we use one two ATP molecules in stage one. 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.
