Which monomer–macromolecule pairing is CORRECT?
AAmino acids → proteins
BGlucose → lipids
CNucleotides → carbohydrates
DFatty acids → nucleic acids
Explanation
Amino acids are the monomers that polymerize via peptide bonds to form proteins. Distractors: Glucose is a monosaccharide — it builds *carbohydrates* (starch, glycogen), not lipids. Nucleotides build *nucleic acids* (DNA, RNA), not carbohydrates. Fatty acids combine with glycerol to form *lipids*, not nucleic acids.
