Question

multiple choice question
the molecule illustrated here is a(n) ______ that can be incorporated into a larger molecule called a ______
monosaccharide; carbohydrate
fatty acid; lipid
nucleotide; nucleic acid
amino acid; protein

Explanation:

Monosaccharides are the building - blocks of carbohydrates, fatty acids are building - blocks of lipids, nucleotides are building - blocks of nucleic acids, and amino acids are building - blocks of proteins. Without seeing the molecule, we rely on the general knowledge of monomers and polymers in biology. Each option represents a monomer - polymer relationship.

Answer:

Since no molecule is shown, all options are conceptually correct in terms of monomer - polymer relationships. But if we assume a general knowledge - based multiple - choice without a specific molecule hint, all of the following are valid:

• A. monosaccharide; carbohydrate
• B. fatty acid; lipid
• C. nucleotide; nucleic acid
• D. amino acid; protein
