WebAn experiment was done to investigate the effects of low pH on enzymes activities. According to Dunaway, Mariano, D. (2008) enzymes are protein in nature. They are used to speed up the rate of reactions. At, the end of the experiment, enzyme is not used up. There are several factors that affect the rate of enzymatic activities. WebFactors that affect the activity of enzymes are: temperature, pH, substrate concentration and enzyme concentration. 1. THE EFFECT OF TEMPERATURE. As the temperature increases the rate of an enzyme-catalyzed reaction also increases. If the temperature is increased by 10°C, the rate of the reaction will double: Rate at x°C.
