Option 2

Prof. Wilson: You are absolutely correct about the definition of the active site. Remember that the active site is the binding site so that the reaction can take place. It is typically a pocket or groove on the enzyme’s surface and provides the optimal binding for the reaction, often involving specific amino acid residues to facilitate the interaction. I suggest you revise the definitions for a substrate and product though. These terms are fundamental to understanding how enzymes function as biological catalysts in various biochemical processes.

Prof. Wilson asks you to reconsider your response.
