Metabolism is a process that occurs within every living cell or organism, it is sum of all chemical processes that happen within the cell. By definition there are many kinds of metabolisms aerobic respiration, anaerobic respiration and fermentation.
Aerobic respiration is the process of breakdown of glucose to produce ATP, which requires presence of Oxygen. Aerobic respiration involves four steps glycolysis, formation of acetyl coenzyme A, the citric acid cycle and electron transport chain. Two enzymes that indicate the presence of electron transport chains (ETCs) are oxidase and catalase. Oxidase is an enzyme that is found in Cytochrome C of ETC. It is found in bacteria and mitochondria of eukaryotic organisms. Organism that possess ETC with directly move electrons to oxygen, which is the final electron acceptor. Catalase is common enzyme, which is found in living organisms. Catalase is very important enzyme that protects cell from hydrogen peroxide; it is very damaging to the cell. Catalase decomposes hydrogen peroxide, into harmless water and oxygen gas. To avoid death cells produce catalase, this results from faulty ETC.
Anaerobic respiration occurs in environments without oxygen gas. Anaerobic respiration only occurs in prokaryotic organisms; …show more content…
In the first part of the test we will be testing the prokaryotic and eukaryotic organism for oxidase and catalase. In the third test we will be testing if either prokaryotic or eukaryotic cells can do fermentation. On the first test we will use BBL Dry Slide to test for oxidase, we will be looking for change of color. In the second test we will be testing for catalase using a drop of hydrogen peroxide on each organism, prokaryotic and eukaryotic. In the third experiments we will be testing if either of the organism can do fermentation, in different products such as glucose, lactose, and
