Conclusion In conclusion, the reason why this lab was conducted to examine the effects of Hydrogen Peroxide coming into contact with a catalase solution, in this experiment it was Calf Liver. As a result of the contact, oxygen gas was formed. Therefore, the collected data suggested the rate of reaction of the catalyse increases as the volume of Hydrogen Peroxide increases. This can be seen through the linear trend line that moves up in a positive direction, which shows that the relationship between the rate of reaction and the volume of hydrogen peroxide is positive. However, the increase in the rate of change is non-constant. When comparing this lab to that of another the results are similar. For example, in both the labs, the decomposition …show more content…
This is significant because the reaction can be altered based on the volume of catalase the Hydrogen Peroxide is exposed to. So with more catalase on the tab, the Oxygen displaced would be increased. However, with less catalase covering the tab, the amount of oxygen displaced will be lowered. An improvement that can be made in order to prevent the uneven amount of liver solution covering the tab, is to measure a specific amount of liver solution for the tab to be dipped into. This would improve the results because the amount of oxygen that will be displaced will be consistent throughout the lab. Thus, by doing …show more content…
This limitation is significant because the pressure of released gas, oxygen, is the dependant variable that is depending on the amount of substrate that the catalase liver solution is exposed to. However, the water droplets would not have been enough to cause the results to be change too much. Using a paper towel to dry the inside of the test tube or a test tube rack to allow the test tube to dry naturally. This improvement will prevent water molecules from mixing into the Hydrogen Peroxide solution and therefore will not act as a physical interference with the substrate and the catalase enzyme.
