How do the number of enzymes in a system change as a chemical reactions progresses?

Question

1. the number of enzymes will decreased over time as they are consumed in the reaction.
2. the number of enzymes stays the same over time because they are produced and consumed in the reaction equality.
3. the number of enzymes stays the same over time because they are not consumed in the reaction.
4. the number of enzymes will increase over time as they are produced during the reaction.

Answer 1

The correct answer is:

3. the number of enzymes stays the same over time because they are not consumed in the reaction.

Enzymes act as catalysts in chemical reactions, which means they facilitate the reaction without being consumed or permanently altered in the process. Once the reaction is complete, the enzymes are available to catalyze additional reactions. Therefore, the overall number of enzymes remains constant during the reaction.
