Investigation to see the effects of increasing the surface area of a potato when mixed with Hydrogen Peroxide.

In my coursework I will investigate about enzymes in potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because, when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on, and with more …

…it and so the active site is changed and the correct molecules may not fit into to make the reaction and for another experiment I could do a experiment where I could see that this is true by using 3 potatoes which have been boiled, which will supposedly denature the enzymes and 3 normal potatoes which will be mixed with the Hydrogen Peroxide to see if the react the same and produce the same amount of oxygen.
