Now, this is known as the glucose Allenine cycle. We call it glucose Allenine because we utilize a glucose here to form pyruvate, to use it to actually attach that ammonium and form that alanine. That's why we call it the glucose Alanine cycle. It cycles between glucose and Alanine, but it's also returned back to its source, the skeleton muscle cell. But the ammonium is transported into the skeletal, into the liver. It's not returned back to the skeleton muscle.
