13. Enzymes work by:

A. Increasing the level of energy that needs to be used to initiate a chemical reaction.
B. Decreasing the level of energy that needs to be used to initiate a chemical reaction.
C. Absorbing energy released by a chemical reaction.
D. Providing energy to be used in a chemical reaction.



Answer :

Final answer:

Enzymes are biological catalysts that lower the activation energy of chemical reactions, facilitating and speeding up the reaction process.


Explanation:

Enzymes are biological catalysts that work by lowering the activation energy of chemical reactions. Activation energy is the energy required to start a reaction, and enzymes facilitate reactions by reducing this energy barrier, thereby speeding up the reaction process.
