Effect of different size beads on the activity of immobilised catalyse Aim: To find out how varying the size of beads containing yeast varies the rate of activity of catalase in a fermentation reaction of hydrogen peroxide with immobilised enzymes. A catalyst is a substance that speeds up the rate of a chemical reaction, without itself being used up in the process however it maybe affected physically i.e. degradation of the surface of the catalyst. Catalysts work by reducing the activation energy needed for a particular reaction by offering a different path for the reaction to take place. Activation energy is the energy, which needs to be supplied before a reaction can occur, basically the amount of energy needed to overcome the bonds between the molecules and atoms. Catalysts are usually specific to one reaction, that is, different reactions need different catalysts. This is the lock and key theory however there is...
