Answer: In humans, proteases are mainly present in pancreatic juice and gastric secretions to break down dietary proteins. Trypsin and chymotrypsin are secreted by the pancreas and pepsin is secreted by the chief cells in the stomach.
Step-by-step explanation:
Proteolytic enzymes or proteases catalyze the breakdown of proteins into shorter polypeptides or amino acids. They undergo proteolysis by hydrolyzing peptide bonds. Also, they are involved in various biological functions like protein catabolism, cell signaling and digestion.
Protease is produced in the stomach, pancreas, and small intestine.It is produced in the gastric chief cells of the stomach lining and 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. Enzymes are secreted from our salivary glands, 1 and then from the cells lining our stomach, pancreas, and large and small intestines. Different types of enzymes are secreted depending on the types of foods that we eat.
Most of the chemical reactions occur in the stomach and small intestine. In the stomach, pepsin is the main digestive enzyme attacking proteins.Proteases enzymes allow for proteolysis, the process that breaks the long, chainlike molecules of proteins so that they can be digested. Proteases are produced by the pancreas, and they are also found in some fruits, bacteria and other microbes
