And it also destabilizes that glucose molecule, increases its overall energy and that makes it more reactive, and that prepares the glucose for stage two. Now, in stage two, we break down that destabilized glucose molecule into two components. And then in stage three, we essentially take those two components, we oxidize those two components and that allows us to actually harvest the energy in those molecules and form ATP molecules, as well as pyruvate molecules and NADH molecules. So let's focus on stage one. So in stage one, we basically want to take that glucose molecule and transform it into fructose one six bisphosphate, and we'll see exactly why that is in just a moment. So actually, if we look at stage one, we can break down stage one into three different steps.
