So how do our cells, cells specifically our liver cells actually regenerate and replenish their supplies of glycogen? This is what I'd like to focus on in this lecture and I'd like to focus on how insulin and how glucose molecules actually affect liver cells. So after adjusting a meal rich in carbohydrates the blood glucose levels in our body rise above the normal five millimolar value. And what our liver cells will try to do is they will try to maintain the proper level of glucose in our blood and they will uptake that glucose into the cell. Now what will also happen is the beta cells of the pancreas will begin to produce and secrete a small peptide hormone known as insulin. And insulin will travel through the bloodstream and eventually will make its way into a special receptor protein found on the membrane of liver cells known as the insulin receptor.
