And so we form the carbonic acid and then the second ATP comes into play. And this basically attaches the phosphate here, attaches onto this oxygen to basically form the carbon oil phosphate as we have it here. And so this molecule is high in energy, it has a high transfer potential because of this anhydrate bond shown here. And so what that means is this molecule is now ready to react with the ornasene in step number two. But before we go to step number two. I have to mention that this carbon oil phosphate synthetase enzyme will only become active in the presence of a molecule known as an acetyl glutamate.
