Now, once the alanine moves into the liver, the alanine basically undergoes this pathway. But in reverse. So we begin with Alanine. Alanine then is formed into glutamate, and then that breaks down into pyruvate and ammonium. So ultimately, what happened is the ammonium that we used here or that we formed here, eventually made its way to the liver. And it's the liver that uses the urea cycle to basically help our body dispose of this toxic substance.
