A) secretin
B) cholecystokinin
C) enterogastrone
D) enterocrinin
Correct Answer: B
Solution :
Bile juice is a yellowish-green or greenish-blue alkaline (pH-7.7) fluid. It contains about 90% water, 60% bile salts, 30/0 bile pigments etc The common bile salts are sodium chloride, sodium bicarbonate, sodium glycocholate and sodium taurocholate. Cholecytokinin directly stimulates-contraction of gall bladder cmd bile now starts. Secretm regulates the secretions .of pancreatic juice, like that of gastric juice Secretm is a single chain polypeptide of low molecular weight with 27 amino acids residue. The entry of lipids into the duodenum apparently causes the liberation of enterogastrone by the intestinal wall which inhibits the gastric juice secretion.
