The hormone produced by the pancreas that regulates blood sugar is which?

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

Answer: (B)

Insulin is the hormone produced by the pancreas that regulates blood sugar. It’s released by the beta cells in the islets of Langerhans when blood glucose rises after a meal. Insulin lowers blood glucose by helping cells—especially in liver, muscle, and fat tissue—take up glucose from the blood, and by promoting storage of glucose as glycogen in the liver while suppressing new glucose production. Glucagon also comes from the pancreas but from alpha cells and increases blood sugar. Adrenaline and cortisol, produced by the adrenal glands, raise blood sugar during stress.
