And what will begin to happen is the epinephrine molecules will bind until liver cells that will initiate a specific type of signal transduction pathway. So remember that epinephrine binds unto the beta anginergic receptor of liver cells and that stimulates epinephrine signaling and that ultimately produces a calcium ions and the rise in calcium inside the cell. What that basically does is it stimulates the phosphatase molecule and the phosphatase basically hydrolyzes this bond and transforms the inactive molecule into its active state. And once this is activated, we'll produce plenty of acetyl coenzyme A molecules needed to produce ACP, so we can continue running away from that scary animal, our bear. Now, insulin. So following a meal that's let's suppose rich in carbohydrates, we're going to see that our blood glucose level will rise and liver cells and other cells of the body will try to maintain that glucose level.
