Now how do we form six ribose five phosphates from these five glucose six phosphates? Well, remember the steps of the non oxidative phase of the penthouse phosphate pathway? In that particular phase we saw that we use three ribose phyphosphates to generate two fructose six phosphates and one glycero aldehyde three phosphate. And so what that means is because we have four fructose six phosphates and two glutaraldehyde three phosphates. If we combine these two we're actually going to form six ribose phosphate molecules because we need two fructose and one gap to form three ribosphosphates. But because we have double that amount, we form not three, but six ribose phyphosate molecules.
