Enzymes make reactions MUCH easier and/or faster by
decreasing the activation energy of the reaction. Which analogy correctly describes
enzymes (A, B, or C)?
a. The aerodynamic shape of a car, like an enzyme, does not supply energy to the car, but it can make it easier for the car to move.
b. Gasoline, like enzymes, provides the energy necessary to make a reaction occur in your car engine.
c. Just like your car will not start without a key, a chemical reaction will not occur without an enzyme.
