Question

question 6 of 10
carbon, hydrogen, and oxygen can combine to form monomers called fatty acids. which type of macromolecule contains many fatty acids?
a. nucleic acid
b. lipid
c. carbohydrate
d. protein

Explanation:

To solve this, we recall the components of each macromolecule:

• Nucleic acids (A) are made of nucleotides, not fatty acids.
• Lipids (B) include fats, which are made of fatty acids and glycerol. Many fatty acids combine to form lipids.
• Carbohydrates (C) are made of monosaccharides (like glucose), not fatty acids.
• Proteins (D) are made of amino acids, not fatty acids.

So the macromolecule with many fatty acids is lipid.

Answer:

B. Lipid
