On top of that, we also have NADH that will bind onto a special site of the isocitrate. It will kick off the NAD plus. And if there is no NAD plus bound to the isocitrate dehydrogenase enzyme. If the NADH is bound instead of the NAD plus step three A cannot take place. And so because that happens, because the NADH kicks off, the NAD plus the isocytrate dehydrogenase enzyme cannot carry out its function. So we see that if we have high levels of ATP, a high energy charge value, we will not need to generate any more ATP.
