How Does an Enzyme Affect the Activation Energy of a Reaction

Multiple Choice

How does an enzyme affect the activation energy of a reaction?

A) It raises the energy of activation,which makes the reaction it regulates less likely to occur and decreases the chemical product yield.
B) It lowers the energy of activation,which makes the reaction it catalyzes less likely to occur and slows down the production of the chemical product.
C) It decreases the energy of activation,which results in more energy being needed to initiate the reaction and increases the yield of the chemical product.
D) It increases the energy of activation,which decreases the likelihood of undesirable side reactions and increases the yield of desired products.
E) It reduces the energy of activation,which makes the reaction it facilitates more likely to occur and speeds up the production of the chemical product.
