Experiment 2: Why did the catalase function level off when different hydrogen peroxide concentrations were tested? High concentrations of hydrogen peroxide raised the pH levels above the point of optimal catalase activity. Catalase activity continually increased, so the experiment must have been done incorrectly to produce results that appeared to level off. High concentrations of hydrogen peroxide caused oxidative damage to the catalase enzymes and they were not able to perform at their optimal level. O At some point, all of the catalase in solution was catalyzing reactions, so even if the hydrogen peroxide concentration was increased, the rate of the reaction could not increase any more.
