In biochemistry, what are the monomers (basic building blocks) that polymerize to form proteins?

• A. Amino acids
• B. Monosaccharides (simple sugars)
• C. Fatty acids and glycerol
• D. Nucleotides

Answer: (A)

Verified step by step guidance

1. Understand that proteins are polymers, meaning they are large molecules made up of repeating smaller units called monomers.
2. Recall that the monomers that polymerize to form proteins are amino acids, which link together through peptide bonds.
3. Recognize that other options like monosaccharides, fatty acids and glycerol, and nucleotides are monomers for different types of macromolecules: carbohydrates, lipids, and nucleic acids respectively.
4. Focus on the structure of amino acids, which have a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a variable side chain (R group).
5. Conclude that amino acids are the correct monomers that polymerize to form proteins by forming peptide bonds between the amino group of one amino acid and the carboxyl group of another.
