PATHOLOGY

Detailed explanation-1: -The several proteolytic enzymes present in the GIT include endopeptidases (trypsin, chymotrypsin, and elastase) and exopeptidases (carboxypeptidase A and aminopeptidase). These proteolytic enzymes are regarded as extracellular barriers and are involved in the degradation of peptides and proteins.

Detailed explanation-2: -Trypsin elastase, carboxypeptidase, and chymotrypsin are produced by the pancreas and released into the duodenum where they act on the chyme. Further breakdown of peptides to single amino acids is aided by enzymes called peptidases (those that break down peptides).

Detailed explanation-3: -This active trypsin acts with the other two principal digestive proteinases-pepsin and chymotrypsin-to break down dietary protein into peptides and amino acids. These amino acids are essential for muscle growth, hormone production and other important bodily functions.
