storage.
2. Which hormone raises blood glucose levels?
A. Glucagon
B. Insulin
C. ADH
D. Aldosterone
,Correct Answer: A. Glucagon
Rationale: Stimulates glycogen breakdown and gluconeogenesis in
liver.
3. Which hormone inhibits both insulin and glucagon secretion?
A. Somatostatin
B. Insulin
C. Glucagon
D. Cortisol
Correct Answer: A. Somatostatin
Rationale: Secreted by delta cells of pancreas to regulate endocrine
activity.
4. Which hormone stimulates glycogen breakdown in liver?
A. Glucagon
B. Insulin
C. Epinephrine
D. Cortisol
Correct Answer: A. Glucagon
Rationale: Maintains blood glucose during fasting.
