- B.α-cells of pancreas secrete insulin✓
- C.Glucagon stimulates glycogenolysis
- D.β-cells of pancreas secrete insulin
Correct Answer
(B) α-cells of pancreas secrete insulin
Solution & Explanation
In the Islets of Langerhans, the α-cells secrete glucagon and the β-cells secrete insulin. Glucagon stimulates glycogenolysis (raises blood glucose). The incorrect statement is that the α-cells secrete insulin — they secrete glucagon, not insulin.
