Question

Insulin is produced by the __________ cells of ______.

• A. alpha cells, liver
• B. beta cells, pancreas
• C. delta cells, pancreas
• D. F cells, liver

Answer 1

The correct option is B beta cells, pancreas

The pancreas is a heterocrine gland that consists of both exocrine and endocrine glandular tissue.

• The exocrine portion of the pancreas is involved in assisting digestion by secreting digestive juices and bicarbonates into the duodenum.
• The endocrine part of the pancreas (islet of Langerhans) produces hormones. Islets of Langerhans are composed of four types of cells - Alpha cells that produce glucagon, beta cells that produce insulin, delta cells that produce somatostatin and F cells that produce pancreatic polypeptide.

Insulin plays a crucial role in regulating blood sugar levels by triggering the cells to uptake glucose which is then converted to glycogen.
