  4. It functions in reverse. It means the enzyme does not determine the direction of reaction, but it only functions in accelerating reaction rate until it reaches equilibrium. The enzyme also functions in substance synthesis and substance breaking down reaction. 
  5. It is required, in small amount. A small amount of enzyme is able to catalyze a chemical reaction.
