Which hormones do stimulate the production of pancreatic juice and bicarbonate?

Answer: (C) Cholecystokinin and secretin. Answer: (c) Cholecystokinin and secretin Solution: Secretin acts on the exocrine pancreas and stimulates secretion of water and bicarbonate ions, while CCK acts on the pancreas and gall bladder to stimulate secretion of pancreatic enzymes and bile juice.

  1. A.Angiotensin and epinephrine
  2. B.Cholecystokinin and gastrin
  3. C.Cholecystokinin and secretin✓
  4. D.Insulin and glucagon

Correct Answer

(C) Cholecystokinin and secretin

Solution & Explanation

Answer: (c) Cholecystokinin and secretin Solution: Secretin acts on the exocrine pancreas and stimulates secretion of water and bicarbonate ions, while CCK acts on the pancreas and gall bladder to stimulate secretion of pancreatic enzymes and bile juice. Together they drive pancreatic juice and bicarbonate output. Gastrin acts on gastric glands (HCl/pepsinogen), not pancreas. NCERT Reference: Chapter 19, Page 247, Line(s) 25-28 — "Secretin acts on the exocrine pancreas and stimulates secretion of water and bicarbonate ions. CCK acts on both pancreas and gall bladder and stimulates the secretion of pancreatic enzymes and bile juice"
