So once again in glycolysis, the three irreversible steps release the majority of the free energy in glycolysis. And that means that for gluconeogenesis to be an effective process, to be a spontaneous process, it must actually somehow bypass these three extremely exergonic steps. And that's exactly what happens. And essentially these three steps are the steps that are used to bypass these three steps here. So let's begin with step number ten. In step number ten, if Gluconeogenesis simply follows the reverse of step ten and Glycolysis, we basically transform Pyruvate into pep.
