Question

the food we eat provides the energy our bodies need. we eat carbohydrates, lipids, and proteins. as food is broken down, the compounds are rearranged through chemical reactions forming new molecules that support growth and provide energy. each biomolecule is made of monomers or building blocks. which of these correctly pairs the macromolecule and its monomer. select all that apply. a lipid: fatty acid b protein: amino acid c carbohydrate: starch d protein: nucleic acid e carbohydrate: monosaccharide

Explanation:

• Lipids (e.g., triglycerides) are composed of fatty acids and glycerol; fatty acids are key monomers.
• Proteins are polymers of amino acids (monomers).
• Starch is a polysaccharide (polymer), not a monomer of carbohydrates.
• Nucleic acids are monomers of DNA/RNA, not proteins.
• Carbohydrates (polysaccharides) are made of monosaccharide monomers.

Answer:

A. lipid: fatty acid, B. protein: amino acid, E. carbohydrate: monosaccharide
