-The digestive system processes food, extracts nutrients, and eliminates the residue.-Trypsinogen, chymotrypsinogen, and procarboxypeptidase break down proteins.-Brush border enzymes like maltase and lactase are released from the small intestine and break down sugars.

Inactive precursors to enzymes are released by this organ to catalyze reactions that digest proteins in the small intestine
Pepsin / ˈpɛpsɪn / is an endopeptidase that breaks down proteins into smaller peptides and amino acids. It is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food. Pepsin is an aspartic protease, using a catalytic aspartate in its active site. [2]
Pepsin is a powerful enzyme in gastric juice that digests proteins such as those in meat, seeds, and dairy products. It is the mature active form of pepsinogen, which is released into the stomach and mixed with hydrochloric acid to produce pepsin.
Pepsin is the first in a series of enzymes that digest proteins. In the stomach, protein chains bind in the deep active site groove of pepsin, seen in the upper illustration (from PDB entry 5pep ), and are broken into smaller pieces.
peptidase: Any enzyme that catalyzes the hydrolysis of peptides into amino acids; a protease. amylase : Any of a class of digestive enzymes that are present in saliva and that break down complex carbohydrates, such as starch, into simple sugars, such as glucose.
The stomach releases gastric juices containing hydrochloric acid and the enzyme, pepsin, which initiate the chemical digestion of protein. Muscular contractions, called peristalsis, also aid in digestion.
Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach.
movement of food particles through the wall of the alimentary canal. The __________ cells of the stomach produce and secrete hydrochloric acid (HCl). What liver secretion is responsible for the emulsification of lipids in the duodenum? Which segment of the small intestine receives chyme from the stomach?
