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 catalyzed 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. We have learnt about the formation of enzyme-substrate complexes, the lock and key model, induced fit model, activation energies of normal …showed first 75 words of 4494 total…

The only assumption one can make is that the quality of the results is variable and therefore only the general trend can be taken into account, which brings us back to approximate proportionality. It is therefore impossible to include the results which I have classed as anomalous in it the conclusion because I can't work out any explanation for the trend or at indeed find a scientific reason for the type of increase demonstrated.
