So in both cases, the alpha keto acid is alpha ketoglutrate. So we use this molecule to basically transfer this green alpha amino group onto the alpha ketoglutrate. Now, when we remove the alpha amino group, this green group from alanine, we basically form pyruvate. When we do the same thing for aspartate, we form oxalo acetate. But because these two molecules are exactly the same, when we transfer that green group onto alpha key to glutarate, we basically form the glutamate. And it's the glutamate that goes on to undergo the oxidative diamondation step to basically abstract that ammonium, as we'll see in just a moment.
