The accurate statement that describes an enzyme is:

**An enzyme is reusable and increases the rate of a chemical reaction by lowering the activation energy.**

Enzymes catalyze reactions by providing an alternative pathway with a lower activation energy, and they are not consumed in the reaction, allowing them to be used repeatedly.
