Answer:
Enzymes are the bio catalyst that are used in biochemical reaction to increase the rate of the reaction. The enzymes has the ability to work at specific pH and temperature conditions.
Enzymes are reusable as they can be used for the further reaction and can be used for the other reactions as well. Enzymes does not undergo any change in the reaction and can be reused in the fresh reactions. Enzymes are not degraded during the reaction catalysis and can be reused in the other reactions of the body.
