What is the effect of an enzyme on the energy of a chemical reaction?

Responses

Enzymes speed up the reaction by lowering the activation energy of the reaction.
Enzymes speed up the reaction by lowering the activation energy of the reaction.

Enzymes decrease the free energy of the reactants.
Enzymes decrease the free energy of the reactants.

Enzymes slow down the reaction by raising the activation energy of the reaction.
Enzymes slow down the reaction by raising the activation energy of the reaction.

The correct response is:

Enzymes speed up the reaction by lowering the activation energy of the reaction.

Enzymes act as catalysts, which means they increase the rate of a chemical reaction by lowering the activation energy required for the reaction to proceed. This allows the reaction to occur more easily and more quickly, without being consumed in the process. The other statements are incorrect with respect to the role of enzymes in chemical reactions.
