Select the biochemical roles of cholecystokinin, or cck. stimulates the secretion of sodium bicarbonate by the pancreas stimulates the secretion of digestive enzymes by the pancreas activates pancreatic zymogens to form active enzymes stimulates the secretion of bile salts by the gall bladder

The CCK stimulates the secretion of digestive enzymes by the pancreas, and stimulates the secretion of bile salts by the gall bladder.

Explanation:

The cholecystokinin (CCK) is a hormone that has a very important role in the digestive processes.

The CCK is secreted by mucosal epithelial cells in the small intestine, specifically the duodenum segment, and has several functions during the digestive process. The CCK stimulates the release of digestive enzymes from the pancreas, and it signals the gall bladder to contract and pour its contents (bile salts) into the small intestine. Other functions are the inhibition of the gastric emptying, the stimulation of the intestinal motility, the secretion of glucagon (together with the hormone gastrin), and the increase of the pyloric sphincter contraction (together with the hormone secretin).
