Which hormone is secreted by the pancreas in response to high blood glucose levels, promoting glucose uptake into body cells?

💡 Solution & Explanation

Insulin is a peptide hormone synthesized by beta cells of the Islets of Langerhans in the pancreas that lowers blood glucose by facilitating cellular absorption and glycogen synthesis. Glucagon raises blood glucose levels by stimulating glycogenolysis, thyroxine regulates basal metabolic rate, and adrenaline mediates fight-or-flight responses. Deficiency of insulin action leads to diabetes mellitus.
