So in the next step, what happens is, once again, we owe and by the way, the amount of energy that is released. And step three is equal to negative 8.4 kilojoules per mole of energy. And actually, the formation of the alpha ketoglutrate is the rate determining step. 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.
