Question

match each structure to the appropriate macromolecule.

Explanation:

• The first structure has peptide bonds and R - groups, which are characteristic of proteins. A peptide bond (-CO - NH -) is formed between amino acids, and each amino acid has an R - group.
• The second structure is a polysaccharide. It is composed of monosaccharide units (hexagonal rings, which are typical of glucose - like units) linked by glycosidic bonds (-O -).
• The third structure has a nitrogenous base (adenine, A in this case), a phosphate group, and a pentose sugar (the five - membered ring). This is the basic structure of a nucleotide, and nucleotides are the building blocks of nucleic acids (DNA or RNA).

Answer:

1. Protein
2. Polysaccharide
3. Nucleic acid
