Insulin is produced by:
Correct answer: B. Beta-cells
- A. Alpha-cells
- B. Beta-cells
- C. Delta-cells
- D. Gamma-cells
Explanation
Insulin is produced by Beta cells, which are found in the islets of Langerhans in the pancreas. These cells play a critical role in regulating blood sugar levels by releasing insulin in response to high blood glucose. Alpha cells, on the other hand, produce glucagon, which increases blood sugar levels. Delta cells secrete somatostatin, which has an inhibitory effect on both Alpha and Beta cells. Gamma cells produce pancreatic polypeptides and are not involved in insulin production.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
