Answer:
{Macromolecule} {Monomer} {Example}
[lipid ] [fatty acid] [cell membrane ]
[protein] [amino acid] [enzyme ]
[carbohydrate ] [sugar ] [starch]
[ nucleic acid] [nucleotide ] [DNA]
Explanation:
Row 1:
Lipids are macromolecules which are made of fatty acids. For example; Cell membrane consists of lipid bilayer.
Row 2:
Proteins are macromolecules and are formed of amino acids, which are joined via peptide linkages. For example; enzymes are globular proteins.
Row 3:
Carbohydrates are macromolecules in which simple sugars may be joined via glycosidic bonds to form oligosaccharides and polysaccharides. For example; starch is a polysaccharide (a form of carbohydrate).
Row 4:
Nucleic acids are made up of nucleotides. Nucleotides have a pentose sugar, a nitrogenous base and a phosphate group. Examples of nucleic acids are DNA and RNA.
