Effect of epinephrine on glucose metabolism in humans: contribution of the liver. Abstract. Epinephrine causes a prompt increase in blood glucose concentration in the postabsorptive state. This effect is mediated by a transient increase in hepatic glucose production and an inhibition of glucose disposal by insulin-dependent tissues. Epinephrine augments hepatic glucose production by stimulating glycogenolysis and gluconeogenesis.
Norepinephrine. In addition to epinephrine, we see norepinephrine, which is a second hormone secreted by the adrenal medulla that increases heart rate, blood pressure, cardiac output and blood glucose levels.So we see that norepinephrine is very similar to epinephrine.t the center of the adrenal glands we see the adrenal medulla. This portion of the gland is stimulated by the sympathetic nervous system to secrete catecholamines, which are hormones that help you deal with short-term stress. There are two catecholamines. One is called epinephrine or adrenaline.
