Once we form this molecule, this molecule is not very stable and it has a very high phosphoryl transfer potential. Why? Well, because this is essentially trapped in the enol state. And it's trapped because this oxygen doesn't have an age, it has this phosphoryl group. And so what must happen in the final stage is this phosphoryl group must be donated to an ADP molecule and replaced with an H. And once it is replaced with an H, it can transform into the more stable ketone state, the Pyruvate molecule. And that's exactly what happens in a final stage.
