Enzymes are remarkable catalysts that facilitate countless chemical reactions within living organisms. Once a reaction is complete, the enzyme’s role in the process is not over. After the reaction, the enzyme undergoes substrate disassembly, where it releases the newly formed product. This step allows the enzyme to be available for subsequent reactions. Furthermore, enzyme-product complex dissociation occurs, breaking the bond between the enzyme and the product and freeing the enzyme from its transient interaction. Finally, the enzyme returns to its original conformation, preparing it for future catalytic cycles.
