Question

Injection of glucagon will

• A. Cause hypoglycemia
• B. Cause galactosemia
• C. Increase blood sugar
• D. Cause goitre

Answer 1

Answer: (C)

Increase blood sugar

Glucagon is secreted from alpha cells of islets of Langerhans of pancreas. It acts on liver cells i.e. hepatocytes and stimulates:

• Breakdown of glycogen i.e. glycogenesis
• Synthesis of glucose from proteins and fats i.e. gluconeogenesis
• Reduced uptake of sugar molecules from blood

Hence, injection of glucagon will increase blood sugar level.

So, the correct answer is 'Increase blood sugar'.
