Enzymatic Activity - Lab Report Example The purpose of the above named experiment is determination of whether the breakdown of hydrogen peroxide is endothermic or exothermic reaction. The experiment is mainly testing two substances. The two different substances are potatoes and meat and preferably beef liver for the purposes of discerning whether there is maintaining breakdown involving different materials. In such an experiment, an exothermic reaction is all about releasing heat energy where there is higher temperature than the initial whereas an endothermic reaction is all about absorption of heat energy and in this case the energy in subject is lower than the initial. Also in this experiment there is Catalase which is a biological enzyme, yeast which showed bubbling. This is similar to the many proteins employed by the human body and used to help in breaking down hydrogen peroxide into oxygen and water through lowering the reaction activation energy. The very substance in subject accelerates chemical reactions but permanently changes or gets used up in the process. It has not yet been proven whether both the liver and the potato contain any Catalase in them. The hypothesis was supported because the liver is a meat while potato is a starch thus both affect how the entire process works in breaking the substances. Several things could be done to improve the experiment including keeping the test tubes much further apart from each other for the purposes of preventing any possible mixing. The second way is keeping every starting temperature constant. As the data shows, tests were started at different temperatures thus not reliable. The third thing is making sure that the thermometers are wiped after every measurement and after every stirring to prevent any possible mixing. The last recommendation would be conducting the experiment in an enclosed space to get better results. The results in the second experiment do not vary much from the
