A fasting patient with diabetes has a blood glucose level of 62 mg/dL but is awake and able to swallow. Which pancreatic hormone normally helps raise the blood glucose level?
Correct answer: A. Glucagon
- A. Glucagon
- B. Insulin
- C. Somatostatin
- D. Amylase
Explanation
Glucagon is released by pancreatic alpha cells when blood glucose falls and promotes glycogen breakdown and glucose production by the liver. Insulin lowers blood glucose, while amylase is a digestive enzyme rather than a blood glucose hormone.

About Endocrine System
The endocrine system covers hormone-producing glands including the pituitary, thyroid, parathyroids, adrenals, pancreas, pineal gland, ovaries and testes. It explains hormone classes, target-cell responses, feedback control, and the functions of hormones such as insulin, thyroxine, cortisol, growth hormone and ADH, which is often confused with a kidney-produced substance.
