Question

Which cells produce glucagon and what is their function?

• A. Source of glucagon - Alpha cells Function - raise the blood glucose
• B. Source of glucagon - Beta cells Function - lower the blood glucose
• C. Source of glucagon - Alpha cells Function - lower the blood glucose
• D. Source of glucagon - Beta cells Function - raise the blood glucose

Answer 1

The correct option is A

Source of glucagon - Alpha cells

Function - raise the blood glucose

The alpha cells present in the Islets of Langerhans, a special group of cells in the pancreas secrete glucagon. Glucagon raises the blood sugar level in the body. It converts the glycogen stored in the liver to glucose. The beta cells in the islets of Langerhans secrete insulin. Insulin enhances the cellular uptake of glucose molecules. They also convert the glucose into glycogen in the liver and muscles.
