Both glucagon and epinephrine act to increase blood glucose levels. However, the action of epinephrine is much faster than glucagon. Select the row below that explains why. Select one: a. Body's Response to Fear Body's Response to Low Blood Sugar Levels The hypothalamus releases ACTH. ACTH tells the adrenal medulla to release epinephrine. Beta cells release insulin into the bloodstream. Insulin tells the liver, muscles, and fat to convert glycogen to glucose. b. Body's Response to Fear Body's Response to Low Blood Sugar Levels The hypothalamus releases ACTH. ACTH tells the adrenal medulla to release epinephrine. Alpha cells release glucagon into the bloodstream. Glucagon tells the liver, muscles, and fat to convert glycogen to glucose. c. Body's Response to Fear Body's Response to Low Blood Sugar Levels Sympathetic neurons send a message from the hypothalamus directly to the adrenal medulla to release epinephrine. Beta cells release insulin into the bloodstream. Insulin tells the liver, muscles, and fat to convert glycogen to glucose. d. Body's Response to Fear Body's Response to Low Blood Sugar Levels Sympathetic neurons send a message from the hypothalamus directly to the adrenal medulla to release epinephrine. Alpha cells release glucagon into the bloodstream. Glucagon tells the liver, muscles, and fat to convert glycogen to glucose.
