Question

An intestinal hormone that stimulates the gallbladder to release bile is

A) secretin.
B) gastrin.
C) enteropeptidase.
D) GIP.
E) cholecystokinin.

Answer 1

The correct answer is E) cholecystokinin

Step-by-step explanation:

cholecystokinin is a peptide hormone which is secreted by the duodenum of small intestine and stimulates the gall bladder to release bile into the small intestine. cholecystokinin give signals to gall bladder to contract which results in the secretion of stored bile from gall bladder into the small intestine through common bile duct.

cholecystokinin also stimulates the secretion of pancreatic enzymes from pancreas. So cholecystokinin plays important role in digestion of food inside the small intestine by facilitating the secretions from gall bladder and pancreas into small intestine.
