gastrointestinal hormone which stimulates insulin secretion (a) gastrin (b) cck (c) secretin (d) GIP

Gastrin- 1)acts on gastric glands 2)Stimulates secretion of HCl & pepsinogen Secretin- 1) acts on exocrine pancreas 2) Stimulates secretion of water and bicarbonate ions CCK (Cholecystokinin)- 1) acts on both pancreas and gall bladder 2) Stimulates the secretion of pancreatic enzymes including insulin and bile juice resp. Gastric inhibitory peptide (GIP) - inhibit gastric secretion and motility. therefore correct answer is (b) i.e Cholecystokinin ( CCK)
