Answer 1

1. Pepsin is the active form of a digestive enzyme in the stomach that breaks polypeptide chains into smaller polypeptides.
2. Cleavage of proteins by pepsin in the stomach results in formation of smaller polypeptides, which get broken down further in the small intestine.
3. An amino acid chain made up of three amino acids joined together is called a tripeptide.
4. Dipeptide describes an amino acid chain made up of two amino acids joined together.
5. The 20 different amino acids are the building blocks used for protein synthesis.
6. Amino acid pools are stockpiles found in the blood and other cells of the body that can be used to build new proteins.
7. The continual process of degrading and synthesizing protein is called protein turnover.
8. Denaturation occurs when a protein is exposed to heat, acid, bases, or mechanical agitation, resulting in unfolding of the protein, though the peptide bonds remain intact.
9. The part of an amino acid that contains nitrogen is called the amine group.
10. The acid group is also known as the carboxyl group.
