Question

Islets of Langerhans produce

• A. ptyalin
• B. insulin
• C. adrenaline
• D. none of these

Answer 1

The correct option is B

insulin

The correct option is B

Explanation of the correct option:

1. Islets of Langerhans also known as pancreatic islets are the regions found in the pancreas that consist of three hormone-producing cells.
2. Islets produce 3 hormones: insulin from beta cells, glucagon from alpha cells, & somatostatin from delta cells.
3. The beta cells of islets of Langerhans produce insulin, and the hormones produced by these cells are secreted directly in the bloodstream which means these are endocrine.
4. Insulin reduces the sugar content in the blood and thus acts antagonistically to glucagon.
   

Final answer: Islets of Langerhans produce insulin.
