Remember, these coenzymes have to be regenerated. So we begin with TPP and we regenerate that TPP so that in the next cycle, this same molecule can be reused by another pyruvate decarboxylation step. Now, let's focus on the cetolipide. So essentially what happens is we break the bond and these two electrons take an H atom, as shown here. And now this is the Cecil group that is ready to be transferred onto the coenzyme A because ultimately, we take this acetyl group off of that pyruvate. So this is the same group that we essentially have here.
