And in this particular case, we're going to basically initiate a signal transduction pathway that activates PKA. And it's the PKA that is responsible for actually initiating the breakdown of glycogen and at the same time stopping or turning off glycogen synthesis. Now, let's suppose our body is at rest or our body just ate a meal that is rich in carbohydrate molecules. 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.
