Which of the following statements about enzymes is false?

• A. Enzymes carry out multiple rounds of a given chemical reaction.
• B. Enzymes accelerate the speed at which reactions get to equilibrium by lowering the activation energy barrier.
• C. Enzymes can denature under highly acidic or basic conditions.
• D. Enzymes push the reaction equilibrium toward product formation.
• E. Enzymes are biological molecular catalysts.

Answer: (D)

Verified step by step guidance

1. Understand that enzymes are biological catalysts that speed up chemical reactions without being consumed in the process.
2. Recognize that enzymes work by lowering the activation energy of a reaction, which allows the reaction to proceed more quickly to equilibrium.
3. Note that enzymes do not change the position of the equilibrium; they only help the system reach equilibrium faster.
4. Consider the conditions under which enzymes can denature, such as extreme pH levels, which can affect their structure and function.
5. Identify the false statement: Enzymes do not push the reaction equilibrium toward product formation; they only accelerate the rate at which equilibrium is achieved.
