C
Water
D
Protein
Verified step by step guidance1
Understand the definition of a macromolecule: Macromolecules are large, complex molecules that are typically composed of thousands of atoms. They are usually formed by the polymerization of smaller subunits called monomers.
Identify common types of macromolecules: The four major types of macromolecules in biological systems are proteins, nucleic acids, carbohydrates, and lipids.
Analyze each option: Nucleic acids (like DNA and RNA) are macromolecules made of nucleotide monomers. Carbohydrates (like starch and cellulose) are macromolecules made of sugar monomers. Proteins are macromolecules made of amino acid monomers.
Consider the nature of water: Water is a small molecule composed of two hydrogen atoms and one oxygen atom (H₂O). It is not formed by polymerization and does not consist of repeating monomer units.
Conclude which option is not a macromolecule: Based on the analysis, water is not a macromolecule because it is a simple molecule, not a large complex structure formed by monomers.
