Enzymes increase reaction rates by
A)increasing the heat of reaction.
B)decreasing the heat of reaction.
C)increasing the activation energy.
D)decreasing the activation energy.

Question

Quizplus · Accepted Answer

Enzymes decrease the activation energy required for a chemical reaction to occur, thus increasing reaction rates. This is accomplished by bringing reactant molecules together and orienting them in a way that reduces the energy required for the reaction to proceed. Enzymes do not affect the heat of reaction.
