Detailed explanation-1: -Enzymes are proteins comprised of amino acids linked together in one or more polypeptide chains. This sequence of amino acids in a polypeptide chain is called the primary structure. This, in turn, determines the three-dimensional structure of the enzyme, including the shape of the active site.

Detailed explanation-2: -Answer and Explanation: The type of macromolecule typically present in enzymes is protein. Proteins are macromolecules formed from smaller molecules called amino acids.

Detailed explanation-3: -Enzymes are mainly globular proteins-protein molecules where the tertiary structure has given the molecule a generally rounded, ball shape (although perhaps a very squashed ball in some cases).

Detailed explanation-4: -Macromolecules are basically polymers, long chains of molecular sub-units called monomers. Carbohydrates, proteins and nucleic acids are found as long polymers. Due to their polymeric nature and large size, they are known as macromolecules.

Detailed explanation-5: -Figure 11.4 Peptides and Proteins are macromolecules built from long chains of amino acids joined together through amide linkages. The identity and function of a peptide or a protein is determined by the primary sequence of amino acids within its structure.
