Function of active site?

The active site of an enzyme is where the substrate binds and the chemical reaction takes place. It provides a specific environment for the reaction to occur, including the correct orientation of the substrate molecules and the presence of amino acid residues that facilitate the reaction. The active site also plays a role in stabilizing the transition state of the reaction, lowering the activation energy required for the reaction to proceed. In summary, the active site is essential for the enzyme to catalyze a specific chemical reaction efficiently.
