Q.Distinguish, in one line, between micromolecules and macromolecules on the basis of their molecular size, and give one example of each.

[!TLDR]

Micromolecules are small (generally under about 1000 daltons), e.g. glucose or an amino acid; macromolecules are large polymers built from many such subunits, e.g. a protein or starch.

[!ANSWER]

Micromolecules are small, low-molecular-weight compounds (e.g. an amino acid or glucose, generally under about 1000 daltons); macromolecules are large polymers built by joining many micromolecule subunits together (e.g. a protein or a polysaccharide such as starch).

Micromolecules are individual small molecules of relatively low molecular weight, such as amino acids, monosaccharides and nucleotides, that make up the acid-soluble pool of a cell. Macromolecules are large polymers assembled by joining many micromolecule subunits together through covalent bonds -- for instance, many amino acids joined by peptide bonds form a protein, and many glucose units joined by glycosidic bonds form starch. Macromolecules make up the acid-insoluble fraction of a cell extract.

Recall the size-based distinction (small subunit vs large polymer built from many subunits) and pair each with one concrete example.
