So let's focus on stage one. So in stage one, we basically want to take that glucose molecule and transform it into fructose one six bisphosphate, and we'll see exactly why that is in just a moment. So actually, if we look at stage one, we can break down stage one into three different steps. We have step one, we have step two and we have step three. So let's quickly go over what each step does and why. So in step one, we basically first formulate one of the carbons on glucose.
