What is a macromolecule?

Explanation:
A macromolecule is a very large molecule formed when many smaller subunits are linked together into polymers. In biology, this includes proteins, nucleic acids, and polysaccharides, which consist of long chains or networks of repeating units and have a high overall atom count. That’s why the best description is a molecule containing a very large number of atoms. The other options refer to smaller entities: a single amino acid is a monomer, and simple sugars or small molecules are not large polymers by themselves.
