Question

Which cells of islets of Langerhans produce a hormone insulin?

Answer 1

The cells of the Islets of Langerhans that produce the hormone insulin are called Beta cells.

Explanation:

The Islets of Langerhans are clusters of cells in the pancreas that are involved in the regulation of blood sugar levels. These clusters contain different types of cells, each of which produces a specific hormone:

• Alpha cells - produce the hormone glucagon, which raises blood sugar levels.
• Beta cells - produce the hormone insulin, which lowers blood sugar levels by facilitating the uptake of glucose into cells.
• Delta cells - produce somatostatin, which inhibits the release of both insulin and glucagon.
• F cells - produce pancreatic polypeptide, which is involved in regulating pancreatic enzyme secretion.

Role of Insulin:

Insulin is crucial for maintaining the balance of glucose in the blood. It helps cells absorb glucose from the bloodstream, thus lowering blood sugar levels and providing energy for the body. Deficiency or resistance to insulin leads to conditions like diabetes mellitus.

Conclusion:

Beta cells in the Islets of Langerhans are responsible for the production of insulin, a vital hormone for regulating blood sugar levels and overall metabolic function.
