So let's see exactly what we mean. So once again we begin with the glucose six phosphate metabolite. We have oxidative phosphorylation take place and we form the two NADPH molecules and the ribose six phosphate. So these molecules basically satisfy this requirement. But what about the ATP? Well the ribosix phosphate can undergo the non oxidative phase of the pentose phosphate pathway to generate the gap, the glyceroaldehyde three phosphates and the fructose six phosphates.
