Question

13. How does an enzyme affect a reaction?

a. changes anabolic reactions into catabolic reactions
b. changes endothermic reactions into exothermic reactions
c. lowers activation energy
d. turns products into reactants

Answer 1

An enzyme affects a reaction by lowering the activation energy required for the reaction to occur.

Step-by-step explanation:

An enzyme affects a reaction by lowering the activation energy required for the reaction to occur. Activation energy is the energy needed to initiate a chemical reaction. Enzymes act as catalysts, meaning they speed up the rate of a reaction by providing an alternative pathway with a lower activation energy. This allows the reaction to occur more quickly and efficiently.
