What is the role of enzymes in metabolic reactions?

  1. Increase the rate of the reaction

  2. Decrease the rate of the reaction

  3. Store energy

  4. Supply energy

The correct answer is: Increase the rate of the reaction

Enzymes play a critical role in metabolic reactions by increasing the rate of the reaction. This is achieved through their ability to lower the activation energy needed for a reaction to occur. Options B, C, and D are incorrect because they do not accurately describe the role of enzymes in metabolic reactions. Enzymes do not decrease the rate of a reaction, nor do they store or supply energy. Rather, they act as catalysts to speed up the reaction.
