Which hormone is produced by the pancreas raises blood sugar by breaking down the stored glycogen?

Question

BlackTom AI · Accepted Answer

The question asks which hormone produced by the pancreas raises blood sugar by breaking down stored glycogen. First, recall the hormones involved in glucose regulation and their typical sources.
Option 1: Oxytocin — produced in the hypothalamus and released by the posterior pituitary; it is not produced by the pancreas and its primary roles are in social bonding, childbirth, and lactation, not glucose metabolism. Therefore this choice is incorrect for the described mechanism.
Option 2: Glucagon — produced by the pancreatic alpha cells; its major action is to promote glycogenolysis in the liver, releasing glucose into the bloodstream and thereby raising blood sugar. This directly fits the mechanism described in the question, making it the correct match.
Option 3: ACTH (adrenocorticotropic hormone) — produced by the anterior pituitary; it stimulates the adrenal cortex to release cortisol, which can influence glucose metabolism indirectly, but it is not produced by the pancreas and its primary action is not glycogen breakdown in the liver. Thus this option is incorrect in this context.
Option 4: Insulin — produced by the pancreatic beta cells; insulin lowers blood glucose by promoting uptake of glucose into cells and storage as glycogen and fat. This is the opposite of the stated mechanism, so this option is incorrect.
Overall, the option that aligns with a pancreatic hormone that promotes hepatic glycogen breakdown to raise blood glucose is glucagon, while the other options do not fit the described mechanism or origin.
