THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Proteases are released by the pancreas into the proximal small intestine, where they mix with proteins already denatured by gastric secretions and break them down into amino acids, the building blocks of protein, which will eventually be absorbed and used throughout the body.

Detailed explanation-2: -Protease. This enzyme breaks down proteins in your diet. It also helps protect you from germs that may live in your intestines, like certain bacteria and yeast. Undigested proteins can cause allergic reactions in some people.

Detailed explanation-3: -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. A low pH (1.5 to 2) activates pepsin.

Detailed explanation-4: -All are stored and secreted from the pancreas as inactive proforms that are activated in the duodenum by trypsin. Trypsin, chymotrypsin and elastase are endopeptidases that cleave specific peptide bonds adjacent to specific amino acids within a protein.
