Question

Which statement about enzymes is correct?

A An enzyme decreases the rate of a chemical reaction.
B An enzyme is shaped to interact with specific molecules.
C An enzyme increases the activation energy of a chemical reaction.
D An enzyme is broken down during a reaction and has to be replaced.

Answer 1

I think it is either A or B but I am not sure. I know a catalyst increases the rate of a chemical reaction but I don't think it is B because I dont believe that an enzyme is shaped to interact with certain molecules. I would go with A or C. The choice is yours.
