What our body will want to do is stimulate the process of glycogen breakdown and stop the process of glycogen synthesis. And what that means is in this particular case our body must also be able to regulate the protein phosphatase one. It basically wants to be able to stop the activity of protein phosphatase one when we want to break down glycogen and when we want to stop glycogen synthesis. So let's focus on the structure of protein phosphatase one. So this is protein phosphatase one and in the active form, protein phosphatase one PP one is attached to a regulatory subunit and that regulatory subunit basically allows the PP one to actually interact with the glycogen and the target enzymes and target proteins. Now, when this signal transduction pathway is activated and we want to basically turn on glycogen breakdown and turn off glycogen synthesis, what the PKA also does is the following two things.
