- D. prolactin
Which pancreatic cells secrete insulin?
- A. Beta cells of the islets
- B. Alpha cells of the islets
- C. Acinar cells only
- D. Adrenal medullary cells
Why can't insulin be given orally to diabetic patients?
- A. Because of structural variation
- B. Its bioavailability will be increased
- C. Human body will elicit strong immune response
- D. It will be digested in Gastro-Intestinal (GI) tract

What is the overall effect of insulin on blood glucose concentration?
- A. It raises blood glucose
- B. It lowers blood glucose
- C. It has no effect on carbohydrate metabolism
- D. It converts glucose into glucagon
Select incorrect statement, regarding chemical structure of insulin.
- A. Mature insulin molecule consists of three polypeptide chains-A, B and C.
- B. Insulin is synthesized as prohormone which contains extra stretch of C-peptide.
- C. C-peptide is not present in mature insulin molecule.
- D. Polypeptide chains A and B are linked by disulphide bridges.
Blood glucose falls during a period without food. Which pancreatic response helps restore it?
- A. Complete suppression of alpha cells
- B. Increased insulin secretion
- C. Increased glucagon secretion
- D. Increased calcitonin secretion
After a carbohydrate-rich meal raises blood glucose, which pancreatic hormone should increase most directly?
- A. Insulin
- B. Glucagon
- C. Adrenaline
- D. Thyroxine
During fasting, falling blood glucose stimulates pancreatic alpha cells to release
- A. glucagon
- B. insulin
- C. aldosterone
- D. oxytocin
After a carbohydrate-rich meal, blood glucose rises. Which hormonal pattern is most appropriate?
- A. Calcitonin becomes the main glucose regulator
- B. Glucagon rises sharply while insulin falls
- C. Both hormones disappear from blood
- D. Insulin rises while glucagon action is relatively reduced
Common mistakes in Pancreas and blood sugar control
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Thinking normal glucagon can substitute for insulin because both come from the pancreas.
- Confuses alpha- and beta-cell hormone production.
- Assumes antagonistic hormones must be unrelated rather than coordinated.
