We take that fructose six phosphate, we use an ATP molecule to transform it into the fructose one six bits phosphate. So this ATP that we use here is the same ATP that is used to actually transform the fifth fructose six phosphate into this fructose one six bits phosphate. And then we basically transform that into, or we break down this into these two intermediates thyroxy acetone phosphate and glycero aldehyde three phosphate. Now this is readily transformed into the glyceroaldehyde three phosphate. And so the SIF glucosex phosphate that goes into this glycolytic pathway is used to form two of these glyceroaldehyde three phosphate molecules. So four of these five glucose six phosphates are used to form four fructose six phosphate.
