What is the effect of enzyme concentration on enzyme activity? Explain how much enzyme activity changes as enzyme concentration decreases, and discuss why this occurs (on a molecular level).

Is this right (and can you add more): As enzyme concentration increases, the enzyme activity increases. This is because, since there is more of the enzyme available, more of it is available to speed up the reaction. More enzyme means more active sites that are available for the substrate to bind to.

  1. YOu have it exactly right. Of course, there is a limit to the effect of increasing concentration to increase rate. As the concentration increases, further increases do no have as much effect on increasing reaction rates.
