Enzyme: hydrogen peroxide and ph essay to test that ph levels affect the activity of catalase in yeast we use these to see how they influence the reaction. Best answer: catalase, as most enzimes, has an optimal ph to achieve its maximum activity (in this case, 70) if you change the ph of the medium either way, you will observe a decline in its activity.
Investigating the influence of ph on the activity of potato catalase the active site is a region of the protein/enzyme such as a cleft or crevice in the tertiary structure of the enzyme, often constituting less than 5% of the surface area - investigating the influence of ph on the activity of potato catalase introduction.
