How Temperature Affects Enzyme Activity

Decent Essays
The overall impact of this study helps understand how temperature affects enzyme activity, and it is apparent that changes in temperature do have an effect on the enzyme catalase. The results obtained in the experiment a give increased insight in the role of enzymes in the human body. The chicken liver is similar to the human liver, and it is clear that catalase works at an optimum temperature of 22°C. This is important because humans maintain a stable body temperature of 37 °C, and with the aid of enzymes this temperature provides enough activation energy for metabolic reactions, in this case the breakdown of hydrogen peroxide into oxygen gas and liquid water. The difference in the two living organisms is 15 C. A possible weakness in this study…show more content…
As, the enzymes found in the liver of a chicken and the enzymes found in a human liver are not too similar what the difference in Celsius between the two maybe due to an error in the experiment. As the data concluded that chicken enzymes worked best at 22 C which does not maintain true with the optimal temperature of a humans which is 37 C. Another possible area for error would be the duration of time that the subjects were exposed to the temperatures. The duration was only a minute and possible could have not given the enzymes enough time to fully create an adequate reaction that allowed them to preform optimally. Our group simultaneously placed the four test tubes in each temperature, it was difficult to obtain an accurate measurement. All four test tubes were removed from their temperatures at the exact same time, but only the hydrogen peroxide was added to one test tube at a time. As my partners and I were conducting the experiment with one test tube, the other test tubes were left unattended and had the time to either cool off or warm up, and this affected the reaction rate and the accuracy of the measurements of each
