And that in turn allows the process of glycogen synthesis to actually take place at the same exact time. Protein phosphatase One also defosphorylates this molecule, inactivating it, and the defuse formulates this molecule also inactivating it. And so this process, the process of synthesizing glycogen is initiated. But the process that leads to the glycogen breakdown basically stops. Now let's go back to this particular case for just a moment. So let's suppose we have low blood glucose levels because of either exercise or fasting.
