Question

Cholecystokinin triggers

• A. release of bile from gallbladder
• B. conversion of proteins to peptones
• C. conversion of fats into glycerol
• D. secretion of gastric juice

Answer 1

The correct option is A release of bile from gallbladder

Cholecystokinin (pancreozymin) is secreted by the epithelium of the entire small intestine. In the pancreas, it stimulates the release of pancreatic juice. In the gallbladder, it stimulates the release of bile.
Proteins are converted into peptones in the presence of pepsin in the stomach, trypsin and chymotrypsin in the small intestine.
Fats are converted into fatty acids and glycerol in the presence of gastric lipase (in stomach), intestinal lipase and pancreatic lipase in the small intestine.
Secretion of gastric juice is under the control of gastrin.
