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: -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). The other type of proteins (fibrous proteins) have long thin structures and are found in tissues like muscle and hair.

Detailed explanation-3: -There are seven types of proteins: antibodies, contractile proteins, enzymes, hormonal proteins, structural proteins, storage proteins, and transport proteins.

Detailed explanation-4: -Only few proteins have the capability to bind the substrate with the help of their active sites in such a manner that allows the reaction to take place in an efficient manner. Hence, all enzymes are proteins but all proteins are not enzymes.

Detailed explanation-5: -All enzymes are proteins. Enzymes are made up of long chains of proteins called amino acids. These chains are held together by peptide bonds to form a 3-dimensional type of structure.
