Which hormone is released to lower blood glucose levels?

Which hormone is released to lower blood glucose levels?

• A. Insulin
• B. Glucagon
• C. Adrenaline
• D. Testosterone

Answer: (A)

When blood glucose rises after eating, insulin is released to bring levels back down. Insulin, produced by beta cells in the pancreas, helps cells—especially in liver, muscle, and fat tissue—take in glucose from the blood. It also signals the liver to store glucose as glycogen (glycogenesis) and reduces glucose production, lowering blood sugar effectively. Adrenaline and glucagon raise blood glucose instead, preparing the body for quick energy during stress or fasting. Testosterone isn’t primarily involved in controlling immediate blood glucose.
