In this particular case, what our body will want to do is it will want the skeleton muscle cells to begin rebuilding the glycogen, to actually replenish the glycogen storage in our cells. And the liver cells will want to uptake some of that glucose from the blood and transform the glucose into glycogen. And in this particular case, our body would want to actually stop the breakdown of glycogen while at the same time turning on the process of glycogen synthesis. And the enzyme that basically plays a key role in this process is known as protein phosphatase One or simply PP One. So what happens when our cells need to regenerate glycogen supplies? Well, an enzyme called protein phosphatase One, PP One, stimulates glycogenesis, the building of glycogen from glucose and turns off glycogen breakdown.
