So we essentially transfer the amino group from Alanine to alpha ketogliate. We form Pyruvate and Glutamate as a result. And the Pyruvate we see is formed in a single step. Now, in the second step, not shown here, we have the glutamate. And we transform that Glutamate into well, we actually release the ammonium, the ammonium group, from the glutamate, and we reform that alpha key to glutarate. And in this process, we have to use an NAD plus or NADP plus, as well as a water molecule to basically remove that ammonium from glutamate.
