I think the correct answer from the choices listed above is option A. Each enzyme produced by the body is specific which means it is only able to catalyze a reaction with a certain molecule. Hope this answers the question. Have a nice day.
Enzymes are specific biological catalysts, that can speed up reactions by lowering the overall activation energy required for the reaction.
There are many different enzymes, and each one is specific to one reaction.
Example: Lactase, is an enzyme that is required in the breaking down of lactose (the sugar found in milk), and lactase cannot catalyse a reaction for the breakdown of starch.
