We form a glutamate and we also form ammonia. And it's this ammonia that is used to basically attach it onto this carboxy phosphate. So we kick off the orthophosphate we attach the amino group onto this carbon to form this carbonic acid. 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.
