Answer: c. Amino Acids
Step-by-step explanation:
Food is chemically and mechanically broken down into smaller particles like building blocks, the smallest of these are a basic unit called monomers. In the stomach, the enzyme pepsin breaks proteins, like those found in salmon, into smaller peptides by splitting the peptide bonds holding the proteins together. The duodenum processes these newly-formed peptide chains or polypeptides, into smaller ones, through the enzyme action of elastase, trypsin and chymotrypsin; these are produced in the pancreas. Peptidases convert these fragments into amino acid monomers for absorption into the bloodstream via the small intestines.
