The correct pairing of a macromolecule with its monomer is Carbohydrate - Monosaccharide.
- Proteins are made up of amino acids, not nucleotides.
- Lipids do not have a specific monomer but are typically composed of fatty acids and glycerol.
- Nucleic acids are composed of nucleotides, not fatty acids.
So, the only accurate pairing from the options provided is Carbohydrate - Monosaccharide.
