Biology coursework decomposition of hydrogen peroxide planning- introduction: in this experiment i will be testing the rate of reaction of the decomposition of hydrogen peroxide using the enzyme catalase when an inhibitor is present . simple experiments on the enzyme catalase aim: the aim of this practical is to use three different techniques to investigate the effect of different concentrations of the enzyme catalase on the rate of breakdown of hydrogen peroxide. Rate of activity of the enzyme catalase in hydrogen peroxide experiment essay sample in this study of increasing target temperature of enzyme catalase coated onto paper filter disks reacting through 3% hydrogen peroxide solution in culture tubes, there was an increase in amount of time taken for the enzyme catalase coated filter paper disks to float to the top of the 3% hydrogen peroxide . Catalase is a substance which is produced by the liver to break down hydrogen peroxide the reaction for the decomposition of hydrogen peroxide is as follows- 2h2o2 (liquid)—catalase --- 2h2o (liquid) + o2 (gas).
- I also predict that at about 50i c the enzymes will start to become denatured which means that the key (the substrate) will not fit into the active site anymore i e.
- Catalase decomposition of hydrogen peroxide has a turn over rate of 5,000,000 molecules (5,000,000 h2o2 molecules are decomposed by one catalase enzyme in one minute) it would require 300 years for the same number of h2o2 molecules to be decomposed without the presence of catalase.
