I did an experiment and i found the ph 8 worked the best, but on the internet it says ph 7 doesdos anyone know what it is for potato catalase and why. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen the optimum ph for human catalase is approximately 7. Introduction to enzymes effects of ph as with activity, for each enzyme there is also a region of ph optimal stability. Message: after having carried out an experiment time how long it takes for a certain amount of oxygen to be produced from the reaction of potato catalase and hydrogen peroxide, i found that a ph of around 4 is the fastest rate for this reaction, but i have read in the archives that it is supossed to be 7. Does anyone know the optimum temperature for catalase in potato's it must be different from human catalase right how does ph affect potato catalase. How does temperature affect catalase enzyme activity with less-than-optimal catalysis taking place at hotter or how does temperature affect catalase enzyme.
