Aim I am going to investigate how the temperature affects the catalyse enzyme on heat content peroxide, using potato discs for the catalyse. guesswork Catalyse is a biological enzyme which works outmatch betwixt 30 and 40 degrees, kindred most enzymes. It also has an best pH. Catalyse breaks down Hydrogen Peroxide into water and oxygen. ground and animal cells contain catalyse. `I foretell that the catalyse enzyme set up in the potato allow for break down the substrate (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 pass on become denatured so molecules of Hydrogen Peroxide wont be able to fit into it and so they cant form an enzyme substrate entangled 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 part of the experim ent. I predict that the graph for the total oxygen evolved will carry like this: I think this because between A and B the rate of response increases the molecules of Hydrogen Peroxide will take up to a greater extent energising energy and so there will be more than collisions, as they run into 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 reply slows down, as the enzyme is eventually denatured. Equipment Stop clock 1 0ml measuring cylinder Delivery tubes Bung !
