So the entire point of stage one is to prepare that molecule for stage two where it basically is cleaved into two identical three carbon molecules. And once it is cleaved in stage two, it's the third stage where we harvest some of that energy, we capture some of that energy to form ATP molecules, as we'll see in just a moment. So as we discuss each one of these individual processes, keep that in mind because ultimately, for instance, in stage one, each one of these reactions takes place and each one of these reactions essentially wants to accomplish that end goal. So each one of these reactions in stage one wants to trap that molecule in the cell and wants to destabilize the molecule, make it more reactive so that eventually it is prepared for stage two to break down into smaller molecules. So let's begin with stage one, process one, step one. So our glucose makes its way into the cyto plasma in the cell.
