Aim I am going to investigate how the temperature affects the catalyze enzyme on heat content peroxide, using potato discs for the catalyse. dead reckoning Catalyse is a biological enzyme which works outmatch amongst 30 and 40 degrees, kindred most enzymes. It excessively has an optimal pH. Catalyse breaks down Hydrogen Peroxide into water and oxygen. lay down and animal cells contain catalyse. `I foretell that the catalyse enzyme build in the potato allow for break down the substratum (Hydrogen Peroxide) quickest at 37- 40 degrees Celsius because enzymes work best at certain temperatures, usually body temperature. If the temperature is above 40 degrees the enzyme give become denatured so molecules of Hydrogen Peroxide wont be able to fit into it and so they cant form an enzyme substrate interlocking and cant be broken down, so no oxygen or water is created. If it is below 37 degrees the amount of activity is reduced, as temperature is a limiting factor in this pa rt of the experiment. I predict that the graph for the total oxygen evolved will control like this: I think this because between A and B the rate of response increases the molecules of Hydrogen Peroxide will deem to a greater extent energising energy and so there will be more than collisions, as they melt down around the container and hit individually other. more(prenominal) enzyme substrate complexes will be formed and so more oxygen and water is formed.

At point B the temperature is the optimum. Between points B and C the temperature is too high for the enzyme to work and the shape of the active post is damaged. The response slows down, as the enzyme is eventually denatured.
