Why do we say that "an enzyme is reusable"?
A) The enzyme does not actively take part in the reaction. It just indicates that the reaction is complete.
B) Enzymes react with the substrate molecules to form products and become denatured in the process.
C) Enzymes ensure that the reaction continues without inhibition even if conditions such as temperature and pH are changed.
D) The products of the reaction are released from the active sites of the enzyme, allowing other substrate molecules to bind with the sites.
