And we'll see why we'll talk about that in much more detail in a future lecture. Now, once we form the alpha key to gluorate, it now undergoes a second oxidative decorboxylation step. Remember, in a citric acid cycle, we have two oxidative decurboxylation steps, and this is the second one. So in step four, we take the alpha key to glutrate. We essentially reacted with coenzyme A, the same coenzyme A that we released in this particular case. And we also have the NAD plus the carrier for the electron.
