But once that process actually takes place and once the glucose levels in our blood return back to normal, the liver cells must be able to actually terminate and shut down glycogen breakdown. So this is what, what I'd like to briefly focus on in this lecture. So we're going to examine five different ways by which liver cells of our body are capable of shutting down glycogen breakdown. Now the first way by which or the first method by which our body is able to actually shut down the Glucagon signal transduction pathway that initiates the Glycogen breakdown is to stop releasing the hormones that initiate this process in the first place. So in this particular case, it's glucagon. So Glucagon is no longer released.
