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. And if we sum up these two individual steps, this is the net reaction that we're going to get noticed. The Co twos will essentially cancel because they're intermediate. And so will these oxalo acetates cancel because they appear on both sides, they're intermediate.
