The lower the activation energy, the _ the reaction will be.
Correct answer: A. Faster
- A. Faster
- B. Moderate
- C. Slower
- D. Both A and B
Explanation
Enzymes function as biological catalysts that significantly enhance the rate of chemical reactions by decreasing the activation energy required for the reaction to proceed. When activation energy is lowered, a larger proportion of the reactant molecules can successfully collide with sufficient. energy to undergo the reaction, thus leading to a faster reaction rate. The incorrect options fail to recognize that a decrease in activation energy exclusively benefits the speed of the reaction rather than maintaining a moderate or slower rate. In summary, the correct answer is faster because enzymes facilitate quicker reactions by reducing the energy barrier.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
