But what about the other product? What about dihydroxyapisode phosphate? So this molecule, unlike this molecule, this one, doesn't actually lie directly on the pathway of glycolysis. And so if this molecule is not actually modified in any way, if we leave this molecule as it is, it will not be able to move on to stage three. And so what will happen is we will essentially lose the potential to form ATP molecules in stage three, because if this one is not modified, it cannot go on to stage three. And so in the next step, what happens is, as we'll see in just a moment, this one is actually transformed into this one via an isomerization reaction.
