What happens to the enzyme after an enzyme-catalyzed reaction?
Correct answer: D. Used for another reaction
- A. Reduced to inactive form
- B. Becomes inert
- C. Changes into substrate
- D. Used for another reaction
Explanation
After an enzyme-catalyzed reaction, the enzyme remains unchanged and can be reused. It catalyzes the reaction by binding to the substrate, forming an enzyme-substrate complex, and then releasing the product(s) while returning to its original state. This allows the enzyme to participate in multiple reaction cycles.

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.
