Now, this carbonic acid is then phosphorylated with a second ATP molecule. So we attach the phosphoryl group onto this carbon on the other side to form the carbon well phosphate. So this molecule now contains an amino group on one side and this highly charged component on the opposing side. And this entire process is catalyzed by single enzyme. Now, once we form carbon well phosphate, this then leaves the active side of CPS and it moves into the active side of aspartade, transcarbolase a different enzyme. What this enzyme does is it takes an amino acid aspartate it attaches it onto this carbon here and it kicks off this orthophosphate group to form carbon oil aspartate.
