A Given Enzyme

Question

A given enzyme
A)can be used for many different kinds of chemical reactions.
B)is permanently changed during a chemical reaction.
C)has a special site where the products bind before the reaction begins.
D)lowers the activation energy of a particular reaction.

Accepted Answer

Enzymes lower the activation energy of a particular reaction, making it easier for the reaction to occur. Enzymes are not permanently changed during a chemical reaction, nor do they have a special site where the products bind before the reaction begins. While some enzymes may be able to catalyze multiple types of reactions, they are generally specific to one or a small group of similar reactions.
