Why does it make sense in liver cells that glucagon and epinephrine have the same effect on glycogen metabolism, which is the exact opposite effect of insulin on glycogen metabolism?
Glucagon and epinephrine signal low blood glucose levels so need to synthesize glycogen, whereas insulin is the fight hormone so need to export glucose.
Glucagon and epinephrine signal a need to import glucose to synthesize glycogen, whereas insulin signals a need to export glucose to the blood. Glucagon and epinephrine signal atheed to raise glucose levels in the blood, whereas insulin signals a need to use glucose to replenish glycogen stores. Glucagon and epinephrine are both derived from nutrients in the blood so signal feeding, insulin is derived from dopamine, so signals hunger.
