And so in the second step, we see that an enzyme called phosphoenol Pyruvate, carboxy kinase or Pep carboxy kinase, converts the oxalo acetate into Pep. Now, carboxy kinase once again means we're coupling the decarboxylation reaction with the phosphorylation reaction. So in this step, the highly energonic phosphorylation of this molecule is coupled with the highly exergonic decarboxylation process. So in two steps, we basically are able to create a pathway that is favorable, energetically. And so we form that phosphorinopyruvate in this two step process. So we have step number one and step number two.
