... of substrate, the enzyme concentration, coenzymes, and enzyme poisons (inhibitors). Discuss how any THREE of these factors can change the rate of activity within cells. Higher Substrate concentration means more enzyme activity because there is an increase in the number of reactions. The activity inc ...
