Explanation
The correct answer is Enzyme. This answer directly addresses the question: What is a biological catalyst called? It matches the approved Chemistry 8462 learning objective and the linked subtopic.

Common mistake
Misunderstanding Catalysts
Students often think that catalysts are consumed in the reaction and therefore do not understand that they can be reused.
Remember that a catalyst is not used up in a reaction; it changes the rate of the reaction by providing an alternative pathway with lower activation energy.
