Detailed explanation-1: -Enzymes are reusable. Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction.

Detailed explanation-2: -As the enzyme catalyzes the reaction and converts the substrate into a product, the product is then released from the enzyme’s active site. The enzyme becomes free again to start another round of reaction in the same way that is by enzyme-substrate complex formation.

Detailed explanation-3: -Like all other catalysts, enzymes are characterized by two fundamental properties. First, they increase the rate of chemical reactions without themselves being consumed or permanently altered by the reaction. Second, they increase reaction rates without altering the chemical equilibrium between reactants and products.

Detailed explanation-4: -Enzymes are catalysts, meaning that they make a reaction go faster, but the enzymes themselves are not altered by the overall reaction.
