Which hormone do beta cells of the pancreas secrete?

Which hormone do beta cells of the pancreas secrete?

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

Answer: (A)

Insulin is the hormone produced by beta cells in the pancreatic islets. When blood glucose rises after a meal, beta cells release insulin to lower it. Insulin promotes glucose uptake into muscle and fat cells, encourages glycogen synthesis in liver and muscle, and stimulates fat storage, while also inhibiting glucose production by the liver. This coordinated action helps restore normal blood sugar levels. Gluagon, in contrast, is made by alpha cells and raises blood glucose during fasting by promoting glycogen breakdown and glucose production. Ghrelin, mainly produced in the stomach, stimulates hunger, and somatostatin from delta cells inhibits the release of several hormones, including insulin and glucagon.
