Final answer:
The enzymes that complete the breakdown of proteins into basic components are pepsin, trypsin, elastase, chymotrypsin, carboxypeptidase, dipeptidase, and aminopeptidase. These enzymes break down proteins into smaller polypeptides, which are then further broken down into smaller peptides and eventually into individual amino acids.
Step-by-step explanation:
The enzymes that complete the breakdown of proteins into basic components are pepsin, trypsin, elastase, chymotrypsin, carboxypeptidase, dipeptidase, and aminopeptidase.
In the stomach, pepsin breaks down proteins into smaller polypeptides. In the small intestine, trypsin, elastase, and chymotrypsin act on the peptides reducing them to smaller peptides. The pancreas produces trypsin, elastase, chymotrypsin, carboxypeptidase, and releases them into the duodenum where they act on the chyme. Further breakdown of peptides to single amino acids is aided by peptidases, such as carboxypeptidase, dipeptidase, and aminopeptidase.
The amino acids are then absorbed into the bloodstream through the small intestines.
