Answer;
C) decreasing the concentration of an enzyme
Explanation;
-Environment factors such as temperature and pH affects the activity of an enzyme. Changing these conditions alters the rate of the reaction caused by the enzyme.
-Each enzyme works at certain optimal conditions such as optimal temperature and optimal pH, thus increasing temperature and pH to optimal levels will increase the rate of enzyme reaction.
-Changing the concentration of enzyme and substrate will also affect the rate of reaction of an enzyme-catalyzed reaction. Increasing enzyme concentration increases the rate of enzyme activity.
