And so the breakdown of glycolysis as it is an extremely exercise process, it takes place spontaneously and irreversibly. So what that means is if gluconeogenesis was simply the reverse of this process, then every time 1 mol of Pyruvate is transformed into 1 mol of glucose, that would require an input of 96.2 kilojoules of energy. And so what that means is gluconeogenesis would be a very, very inefficient and expensive process. And so gluconeogenesis, for that reason, cannot be simply the reverse of glycolysis. So once again, gluconeogenesis is essentially the conversion of Pyruvate into glucose, which is the opposite of what happens in the process of glycolysis. However, gluconeogenesis does not simply follow the reverse steps of glycolysis.
