Answer 2

A) Active Site.

Step-by-step explanation:

An active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. The substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme. The active site usually has the residues that form bonds which are for the time being with the substrate are known as the binding site and the residues that catalyze a reaction of that substrate are known as the catalytic site.
