Which hormone is released in response to high blood glucose levels?

• A. Insulin
• B. Glucagon
• C. Ghrelin
• D. Leptin

Answer: (A)

High blood glucose triggers insulin release from the pancreas. Insulin lowers blood sugar by helping cells, especially in muscle and fat tissue, take in glucose from the blood. It also signals the liver to store excess glucose as glycogen and to promote fat synthesis, which further reduces circulating glucose. In contrast, glucagon rises blood glucose when it’s low by promoting glucose production in the liver, while ghrelin stimulates appetite and leptin regulates energy balance. So, insulin is the hormone released in response to high blood glucose.
