So in the final step, we have the enzyme Biden CO2 complex that we basically formed here that is mixed with that Pyruvate molecule and that forms that oxalo acetate. So we're able to actually use this very activated and reactive complex to attach that CO2 on the oxyloacetate molecule. And so if we sum up these reactions, we essentially get this net reaction here. And again, I have to emphasize that the coenzyme we call acetyl COA is required for the CO2 to bind to that binding. And without it, that binding will not take place. And actually, as we'll discuss in more detail in a future lecture, this actually creates a very important, a very important regulatory point of the process of glucosegenesis.
