The effect of concentration in the rate of enzyme catalysed reaction Aim: To investigate how altering the concentration of the substrate, hydrogen peroxide, affects the rate of a catalytic reaction. Hydrogen peroxide (H202) is a toxin, which is a by-product of metabolism, namely anaerobic respiration. Hydrogen peroxide (H202) is a colorless and transparent liquid, which is relatively stable and so requires the presence of catalase in order to decompose during anaerobic respiration. It is a poisonous toxin and must be broken down into harmless by-products in order to be removed from the organism's body. Catalase is one of the fastest acting enzymes in an organism's body. It catalyses hydrogen peroxide, producing water and oxygen. A single molecule of the globular protein decomposes 40,000 molecules of H202 per second. The catalase is responsible for producing 1012 molecules of oxygen per second. For this experiment, I am going to use yeast as the...
