Explanation:

Step1: Recall effect of catalysts

Catalysts lower the activation energy of a reaction.

Step2: Understand role in cells

In cells, catalysts (enzymes) increase the rate of reactions to maintain homeostasis.

Step3: Know property of catalysts

Catalysts are not consumed in the reaction.
