Answer 1

The statement that accurately describes an enzyme is:

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

Enzymes are biological catalysts that can be used multiple times without being consumed in the reaction. They facilitate chemical reactions by lowering the activation energy required for the reaction to occur, thereby increasing the reaction rate.
