For this catalase experiment it was decided that the group was to keep the concentration of catalase and hydrogen peroxide the same and only change the level of pH buffer throughout the experiments conducted. This was done to observe the effect different levels of pH buffers have on the breakdown of hydrogen peroxide and the volume of oxygen released. The results from the majority of experiments conducted reflect that though they are in consensus with the hypothesis that the volume of oxygen will be at its highest at pH 7, it was found that the temperature of hydrogen peroxide and the batch of catalase may have varied which affected the precision of the results throughout the weeks of experimentation (see graphs in results section).
Experiment 2 indicates that there were substantial errors and inaccuracies which occurred. Unfortunately, the main cause/s of the errors are unknown but, it is believed to have transpired due to the groups mistake of measuring out both pH 3 and 5 …show more content…
In this experiment method and all of the materials remained the same except for the replacement 4ml of catalase with 4ml of room temperature distilled water. Table 1 shows that the volume of oxygen released/ produced is much greater when catalase is involved in the equation. Although, even without catalase, pH 7 is still the optimal level.
The results we arrived at fit into the big picture by showing that pH does in fact affect the productivity/ ability to speed up chemical reactions. The faster catalase could break hydrogen peroxide into oxygen and water the faster that it could speed up chemical reactions in the bodies or organisms. The results, at first may seem dry, but they demonstrate how crucially important it is we know what the optimal pH is for enzymes like catalase. This knowledge allows us to understand better our bodies, and the chemical reactions inside it, as well as enable us to protect the systems that we depend on to stay
