Hydrogen peroxide reacting with potato to produce oxygen and water Planning experimental procedure: An enzyme is a biological protein which speeds up or catalyses chemical reactions in living things. They can allow the reaction to occur when it would not have done so otherwise, for example at a lower temperature. I am going to find out if the enzyme in potato catalyses the reaction where hydrogen peroxide (H2O2) breaks down to water (H2O) and oxygen (O2). In order to find out more about the reactions I will change one of the variables and measure the outcome. The variables are the amount of enzyme, as shown by the surface area of potato and the amount of hydrogen peroxide, as shown by its concentration in solution. The easiest outcome to measure is the amount of oxygen (O2) produce. Another outcome is the amount of water (H2O) produced, but this is a smaller volume as...
