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. So we have to have an acetyl glutamate to actually activate the carbon well phosphate synthetase to allow it to undergo these reactions and produce carbon well phosphate. And because this enzyme lies in the matrix of the mitochondria, this step takes place in the matrix of the mitochondria. Now step two also takes place in the matrix of the mitochondria because the enzyme ornithine transcarbomolase lies in the matrix of the mitochondria.
