Also the more Hydrogen Peroxide added the more likely gas given off will increase. Is it better to use peroxide or alcohol? The enzyme was able to catalyze the reaction more quickly. It is able to speed up the decomposition of Hydrogen Peroxide because of the shape of the Hydrogen Peroxide molecule. This is because as you cut it up into smaller bits, you make the surface area greater meaning there are more enzymes to react with each other, and there will be more successful collisions between the two reactants. The potato contains less of the enzyme catalase, therefore requires more activation energy, slowing down the rate of reaction. If I was to do the experiment again I would understand it more and get more accurate results.

If they get hotter than this temperature, which is usually about 45°C some have certain microbes which can work at higher temperatures the enzyme dentures and stops working. Rubbing alcohol is good for killing bacteria such as E. Catalase is an anti-oxidant that converts hydrogen peroxide into oxygen and water. Which potato has the most catalase? I would also use something other than a potato as my source of enzyme. A larger amount of catalase lowers the activation energy, therefore speeds up the rate of reaction. Other experiments show the presence of oxygen. Takedown request What enzyme in potato reacts with hydrogen peroxide? Effects of Temperature As the temperature increases toward the optimum point, hydrogen bonds loosen, making it easier for catalase to act on hydrogen peroxide molecules.
