- D. They change the products of the reaction.
Answer
They act as catalysts to speed up reactions.
Explanation
The correct answer is They act as catalysts to speed up reactions.. This answer directly addresses the question: What is the role of enzymes in biological reactions? It matches the approved Chemistry 8462 learning objective and the linked subtopic. The other options are incorrect because they either change the rate, catalyst, reversible reaction, equilibrium, or graph context, or they do not answer the exact point being tested.
Common mistake
Misunderstanding Enzyme Function
Students often think that enzymes are consumed in the reactions they catalyze.
Remember that enzymes are not used up in the reaction and can be reused multiple times.
