Single science Coursework Investigating the effects catalyse has on hydrogen peroxide solution Aim: I am going to investigate the effects which catalyse has on a hydrogen peroxide solution Preliminary work We would use potato to do the experiment because we had done a previous experiment when we put a piece of potato and liver into a hydrogen peroxide solution and the rate of reaction for the liver was too fast to measure and time.

Theory Enzymes are special shaped protein molecules which act as catalyst and work in living organisms. Enzymes help speed up the rate of reactions. Each enzyme has a unique 3D shape which means that they work with certain types of substrates. This is also known as 'lock and key' because the shape of the substrate fits
