Answer: The statement that is true about enzymes is:
Enzymes lower the activation energy of a chemical reaction.
Explanation:
Enzymes act as biological catalysts, facilitating chemical reactions by lowering the activation energy required for the reaction to occur. This allows the reaction to proceed more readily and at lower temperatures, making it more efficient. Therefore, enzymes do not decrease the rate of a chemical reaction, leave the activation energy unchanged, raise the activation energy, or increase the temperature of a chemical reaction.
