Biology · Secondary 3 · Easy · Planning an investigation
In an experiment on catalase, a student keeps the volume and concentration of hydrogen peroxide, the mass of potato, and the temperature constant. Only the pH is changed. Why is this good experimental design?
- It increases the total amount of oxygen produced
- It ensures that only pH affects the rate of reaction
- It makes the reaction finish more quickly
- It prevents the enzyme from denaturing
