Investigating the enzyme Catalase-AS biology coursework Introduction The experiment being carried out will find the effects of the enzyme catalase with different concentrations of substrate. . This enzyme is common in living organisms and its function is to catalyze the decomposition of hydrogen peroxide to water and oxygen. Hydrogen peroxide is a poisonous by product of metabolism, it can kill cells. Catalase from a potato will be used. An enzyme is a protein produced by any living organism which acts as a catalyst in specific reactions without being used up. All cells produce H2O2 2H2O2 › 2H2O + O2 in Metabolism. It is toxic so it is broken down by catalase. The factors that affect the enzymes are: Temperature changes - catalase works well at high temperatures up to 45°C. This is because they gain kinetic energy so the move around faster, more substrates can be broken down in the same amount of time. After...
