And so, for instance, we know that in step ten of glycolysis we transform Pyruvate into phosphorino Pyruvate by using a very exergonic process. And so if we simply reversed that step in gluconeogenesis, this reverse step would be very endergonic. It would require a large input of energy. So to basically bypass that highly endergonic process, we create a different process, a different reaction pathway that bypasses it, and this is a much more favorable reaction. So in a two step process, we're able to actually transform the Pyruvate molecule into a phosphate ENL Pyruvate by using a favorable reaction pathway. So let's begin by focusing on step number one.
