Question

question #12
enzymes are a diverse class of macromolecules that have many important functions. what is true about enzymes?
a they slow down chemical reactions.
b they raise the activation energy of reactions.
c they can be re - used in multiple reactions.
d they are not affected by changes to temperature and ph.

Explanation:

Enzymes are biological catalysts. Catalysts speed up chemical reactions by lowering the activation energy. They are not consumed in the reaction, so they can be reused. Enzymes are affected by temperature and pH (denaturation can occur).

Answer:

C. They can be re - used in multiple reactions.
