WebFeb 4, 2024 · Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme will increase until it reaches optimum pH range (pH 7) because the enzyme is less denatured when it reaches the preferred pH level, and after this, it will decrease because the active site will change in shape and it will no longer accept … WebMay 29, 2024 · How does pH affect peroxidase activity? Peroxidase activity ceases at a pH of 2.5 or 8.5 to 9.5. Lower pH levels result in a more effective inactivation of the enzyme than do higher pH levels, meaning that acidic environments are more effective inhibitors of peroxidase activity than basic environments.
