Cholecystokinin (CCK), formerly called pancreozymin, is a digestive hormone released with secretin, when food from the stomach reaches the duodenum. Cholecystokinin causes contraction of the gallbladder, which forces bile into the duodenum.
Secretin stimulates the release of a watery bicarbonate solution from the pancreatic and bile duct epithelium. Secretin increases water and bicarbonate secretion from duodenal Brunner's glands to buffer the incoming protons of the acidic chyme. It also enhances the effects of cholecystokinin to induce the secretion of digestive enzymes and bile from pancreas and gallbladder, respectively.
Which of the following belongs to the class of pepsin and trypsin?
Chymosin, known also as rennin, is a proteolytic enzyme related to pepsin that synthesized by chief cells in the stomach of some animals. Its role in digestion is to curdle or coagulate milk in the stomach, a process of considerable importance in the very young animal.
