How does the number of enzymes in a system change as the chemical reaction progresses?

Question

1. Number of enzymes stay the same because they are produced and consumed in a reaction equally.
2. Number of enzymes will decrease over time as they are consumed in the reaction.
3. Number of enzymes will increase over time as they are produced during the reaction.
4. Number of ezymes stay the same over time because they are not consumed in the reaction.

Answer 1

The correct answer is:

4. Number of enzymes stay the same over time because they are not consumed in the reaction.

Enzymes act as catalysts in chemical reactions, meaning they facilitate the reaction without being consumed or permanently altered in the process. Therefore, the total number of active enzymes remains relatively constant throughout the reaction, although their availability may fluctuate based on various factors like conditions or inhibition.
