Question

a polypeptide is a polymer formed from the bonding of many smaller subunits. what is the monomer that makes up a polypeptide?

• nucleotide
• amino acids
• fatty acid
• monosaccharide

Explanation:

To determine the monomer of a polypeptide, we analyze each option:

• Nucleotides are monomers of nucleic acids (like DNA/RNA), not polypeptides.
• Amino Acids: Polypeptides (and proteins) are polymers formed by the peptide bonding of amino acids. So amino acids are the monomers of polypeptides.
• Fatty acids are components of lipids (like triglycerides), not related to polypeptides.
• Monosaccharides are monomers of carbohydrates (like starch, glycogen), not polypeptides.

Answer:

B. Amino Acids
