An investigation to measure the rate of reaction of hydrogen peroxide decomposition by catalase in yeast For this investigation I have been asked to investigate (by experimentation) the effect of substrate concentrations on the rate of the decomposition of hydrogen peroxide when catalysed by the enzyme catalase. This is part of our work on the function of enzymes, how they work and the effects of conditions on how they work. This experiment will look at various concentrations of substrate and enzyme, and will also look at how this will affect the rate of decomposition, using graphs and tables. In organisms, hydrogen peroxide is a toxic waste product of metabolism. Hydrogen peroxide on its own is relatively stable and each molecule can stay in this state for a good few years. Its decomposition therefore needs to be speeded up greatly in order to prevent it from intoxicating the cell. This is...
