Explanation / Answer

Answer:

1. _Pepsin__is the active form of a digestive enzyme in the stomach that breaks polypeptide chains into smaller polypeptide.

2. Cleavage of proteins by pepsin in the stomach results in formation _Polypeptide strands__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 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 body that can be used to build new proteins.

7. The continual process of degrading and synthesizing protein is called_Protein turnover__.

8. _Denaturatuion_occurs when a protein is exposed to heat, acid, bases or mechanical agitation resulting in unfolding of the protein, through the peptide bonds remain intact.

9. The part of an amino acid that contains nitrogen is called the_amino group__.

10. The _acid group__is also known as the carboxyl group
