And in the process, there are two different things that take place. Number one is we essentially undergo the process of decarboxylation where this CO2 group is actually released. And number two, we also phosphorylate this oxyloacetate into this molecule. Now, when we phosphorylate the molecule that actually requires energy. And so if this reaction just took place with phosphorylation, that would mean an energy input would be required. But because we essentially couple the exothermic, the exergonic decarboxylation with the endergonic phosphorylation, this process basically the sum of those processes basically creates a favorable reaction.
