Purpose: The purpose of this project is to find out the effect of the enzyme activity by looking at enzyme concentration, substrate concentration, and the effect of pH and temperature on enzyme activity. Hypothesis: If procedures are followed correctly then the effect on enzyme activity will be found. Materials: Catalase Hydrogen Peroxide 3% and 1.0 % Forceps Filter Paper Discs Water Ice Water Baths Vials Marking Pencils Stopwatch or Timer Procedures: 1. Gather all materials 2. Set up 5 vials containing 40…showed first 75 words of 558 total…

…showed last 75 words of 558 total…the effect of substrate concentration on enzyme activity? As the concentration of the substrate went up the activity increased. As the concentration of the substrate went down the activity decreased. 3. What is the effect of pH on enzyme activity? PH factor increases (from a base to acid) as the time of the enzyme activity increases. 4. What is the effect of temperature on enzyme activity? As the time of the enzyme activity decreases the temperature increases,
