Hydrogen peroxide naturally breaks down into oxygen and water over time. When exposed to the enzyme catalase, hydrogen peroxide is rapidly converted into oxygen and water.

What feature of catalase most likely is responsible for the change in the rate of conversion of hydrogen peroxide into water and oxygen?

A, Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy.

B, Catalase bonds permanently with the reactants causing hydrogen peroxide to rapidly break down by increasing the activation energy.

C ,Catalase has a flexible structure that allows it to bind and convert any small hydrogen containing compound into water and oxygen.

D, Catalase remains intact, so small amounts of it convert large amounts of hydrogen peroxide into water and oxygen immediately.
