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
e

Explanation:

The question asks to pair macromolecules with their monomers. Lipids (e.g., triglycerides) are composed of fatty acids and glycerol, so fatty acids are key monomers for lipids. Proteins are polymers made of amino acid monomers linked by peptide bonds. Starch is a polysaccharide (a type of carbohydrate polymer), not a monomer—carbohydrate monomers are monosaccharides like glucose. The text for options D and E is unclear in the image, but based on standard biomolecule pairing, A and B are correct.

Answer:

A. lipid: fatty acid, B. protein: amino acid
