In this particular case, at the same exact time, the PKA alsophosphorylates an inhibitory protein molecule. So this is our inhibitory protein molecule in the form that is not attracted to the PP one. But once it phosphorylates it, this becomes attracted to the PP one and it goes on and binds unto protein phosphatase one. And once these two things take place, once the regulatory subune dissociates from PP one and once the phosphorylated inhibitory molecule binds onto protein phosphatase one it puts it into the fully inactive form. So basically PKA doesn't only inactivate glycogen synthase A, it also actually inactivates the protein phosphatase one. And that's what allows this signal transduction pathway to actually turn off the process of glycogen synthesis while at the same time turning on the process of glycogen breakdown.
