What is the general function of enzymes?

• A. To increase the activation energy of a reaction
• B. To slow down chemical reactions
• C. To speed up chemical reactions
• D. To change the equilibrium of a reaction

Answer: (C)

Enzymes play a crucial role in biochemical reactions by acting as catalysts. Their primary function is to speed up chemical reactions without being consumed in the process. They achieve this by lowering the activation energy required for a reaction to proceed, making it easier for reactants to be converted into products. This increase in the reaction rate is essential for sustaining life, as many biological processes occur too slowly at normal body temperatures without the facilitation provided by enzymes. Furthermore, while enzymes can influence the rate of a reaction, they do not alter the equilibrium position of the reaction; they simply help both the forward and reverse reactions reach equilibrium more quickly. Thus, the correct answer highlights the critical role enzymes play in enhancing metabolic efficiency.
