Which term is the monomer that serves as the building block of proteins?

• A. Monomer
• B. Amino Acid
• C. Ester
• D. Substituted Hydrocarbon

Answer: (B)

Proteins are built from small units called amino acids, which are the actual monomers that form the protein polymer. Each amino acid has the parts needed to connect with others through peptide bonds, creating a growing chain that folds into a functional protein. Among the options, the amino acid is the specific building block used to construct proteins. The word monomer is a general term, but when asking what builds proteins, the correct unit is an amino acid. An ester is a different type of chemical compound, and a substituted hydrocarbon is too broad and not the building block of proteins.
