How do enzymes contribute to the transition state of a reaction?

• A. They do not affect the transition state
• B. They create a higher energy barrier
• C. They stabilize and facilitate the transition state formation
• D. They eliminate the need for a transition state

Answer: (C)

Enzymes play a crucial role in biochemical reactions by stabilizing and facilitating the formation of the transition state. The transition state is a high-energy state that occurs during a reaction when the reactants are converted into products. Enzymes work by providing an alternative reaction pathway with a lower activation energy, which helps to stabilize the transition state. When enzymes bind to substrates, they often change the conformation of the substrate, bringing it into a position that is more favorable for the reaction to occur. This lowers the energy required to reach the transition state, making it easier for the reaction to proceed. By stabilizing the transition state, enzymes effectively increase the rate of the reaction without changing the overall energetics of the reactants and products. The other options do not accurately represent the role of enzymes in relation to the transition state. Enzymes do indeed influence the transition state, and rather than creating a higher energy barrier, they actually lower the energy barrier to facilitate the reaction. Additionally, enzymes do not eliminate the need for a transition state; rather, they assist in reaching this state more efficiently.
