which of the following is incorrectly matched?
○ amino acid: protein
○ cholesterol: triglyceride
○ monosaccharide: carbohydrate
○ nucleotide: nucleic acid
question 14

Explanation:

• Amino acids are the building blocks of proteins, so this match is correct.
• Cholesterol is a type of steroid (lipid), while triglycerides are another type of lipid. Cholesterol is not a building block of triglycerides, so this match is incorrect.
• Monosaccharides (like glucose) are the monomers of carbohydrates, so this match is correct.
• Nucleotides are the monomers of nucleic acids (DNA and RNA), so this match is correct.

Answer:

B. cholesterol: triglyceride
