And so the phosphorynopyrulvate is much more likely to donate one of its phosphoryl groups onto that ATP molecule because ultimately, in the final step, step ten of Glycolysis, step five of stage three, we want to form ATP molecules. So in the next step, this is the reaction that takes place. We take this phosphorinopyruvate, also known as pep. Sope this is the molecule here. And so now we're going to basically label this phosphoryl group here. And in the presence of ADP, this molecule here is very highend energy.
