Detailed explanation-1: -An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over.

Detailed explanation-2: -A fundamental task of proteins is to act as enzymes-catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.

Detailed explanation-3: -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-4: -Enzymes are proteins that act as catalysts in biochemical reactions. Common types of catalysts include enzymes, acid-base catalysts, and heterogeneous (or surface) catalysts.

Detailed explanation-5: -When there is an increase in the rate of a chemical process by a biological molecule typically an enzyme, the process is known as enzyme catalysis. Such processes involve chemical reactions and the catalysis generally occurs at a localized site known as the active site.
