Detailed explanation-1: -The active site of an enzyme is the part of the enzyme where substrate molecules bind and a chemical reaction takes place. The active site is made up of amino acid residues that establish temporary bonds with the substrate (binding site) as well as residues that catalyse that substrate’s reaction (catalytic site).
Detailed explanation-2: -The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens).
Detailed explanation-3: -The substrate binds to the enzyme by interacting with amino acids in the binding site. The binding site on enzymes is often referred to as the active site because it contains amino acids that both bind the substrate and aid in its conversion to product. You can often recognize that a protein is an enzyme by its name.
Detailed explanation-4: -The active site is a groove or crevice on an enzyme in which a substrate binds to facilitate the catalyzed chemical reaction. Enzymes are typically specific because the conformation of amino acids in the active site stabilizes the specific binding of the substrate.
