So what that basically means is for gluco neogenesis to actually take place effectively, it must somehow be able to bypass these three steps. In fact, that's exactly what happens as we'll see in a future lecture. Gluconeogenesis and glycolysis actually have seven steps in common, but three steps are not in common and it's these three steps. And that's because glucaneogenesis, if it simply reversed these steps. So for instance, if we look at step ten, if gluconeogenesis went from Pyruvate to Pet, by using this specific reaction pathway, it would need to use 16.7 kilojoules per mole of energy. And to prevent this from happening, to make this reaction, this step, an exergonic step, it uses a completely different pathway to transform Pyruvate into that phospholenyl Pyruvate molecule.
