Concept:Proteins are polymers made of amino acid units joined together by peptide bonds.
Explanation:To obtain amino acids, the protein chain must be broken down into its individual monomers.
This breakdown takes place when water (
H2O) is added to the protein structure.
The chemical process of breaking bonds using water is known as hydrolysis.
Hydrolysis breaks the peptide bonds between adjacent amino acid units.
Once these bonds are cleaved, free amino acid molecules are released.
Hence, proteins are converted into amino acids specifically by hydrolysis, not by oxidation, polymerisation, or reduction.
Answer:A. Hydrolysis
