Question

Which of the following statements is false with respect to an enzyme's ability to catalyse a reaction?

• A. An enzyme provides a reaction surface and a suitable environment for the reaction to take place.
• B. An enzyme binds reactants such that they are positioned correctly and can attain their transition-state configurations.
• C. An enzyme allows the reaction to go through a less stable transition state than would normally be the case.
• D. An enzyme can weaken bonds in reactants through the binding process.

Answer 1

Answer: (C)

An enzyme allows the reaction to go through a less stable transition state than would normally be the case.

An enzyme allows the reaction to go through a more stable transition state than would normally be the case. An enzyme provides an alternate pathway having lower activation energy. The statement (C) is false with respect to an enzyme's ability to catalyses a reaction.
