Question

Choose the correct answer from the alternatives given.
Glucagon secreted by the alpha cells of islets of Langerhans converts:

• A. glycogen into glucose and increases the concentration of blood sugar
• B. sucrose into glucose and fructose, and increases the concentration of blood sugar
• C. glucose into glycogen and decreases the concentration of blood sugar
• D. glucose into glycogen and Increases the concentration of blood sugar

Answer 1

The correct option is A glycogen into glucose and increases the concentration of blood sugar

Glucagon is a peptide hormone, produced by alpha cells of the pancreas. Glucagon causes the liver to convert stored glycogen into glucose which is released into the bloodstream. Glucagon reduces the cellular glucose uptake and utilization. Thus, glucagon is a hyperglycemic hormone.

So the correct answer is glycogen into glucose and increases the concentration of blood sugar.
