So faracell needs to build, for instance, DNA molecules. It needs to use, it needs to have a supply of ribose phosphate. So once again in this particular case, when our cells need the NADPH as much as they actually need the ribose phyphosphate, this is what the cell will carry out. So it will not carry out the glycolytic pathway and it will not carry out the non oxidative phase of the penzosphosphate pathway. Instead, it will only carry out the oxidative phase of the pathway, the pencil phosphate pathway. Why?
