Only anaerobic respiration utilizes an electron transport chain Both differ in the final electron acceptor. ATP is then used as energy by nearly every cell in the body -- the largest user being the muscular system. The major difference between aerobic and anaerobic respiration is the final electron acceptor at the end of the electron transport chain. A final or terminal electron acceptor is a molecule that accepts electrons right at the end of a chain of electron transfer. A final exothermic reaction is the combination of hydrogen with oxygen, to form water. Anaerobic respiration : does not use oxygen. In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is Oxygen.

Both aerobic and anaerobic respiration use electron-transport chain-reaction pathways in energy production. Anaerobic respiration is a form of respiration using electron acceptors other than oxygen. So the respiration which occurs in the presence of oxygen is called as aerobic respiration, on the other hand, respiration occurring in the absence of oxygen is known anaerobic respiration. Does aerobic respiration produce 38 ATP? 3). Is the electron transport chain aerobic or anaerobic? It is the common process carried out in all types of organisms except some ancient bacteria and archaea. Since molecular oxygen serves as the final electron acceptor in the electron transport chain, the cellular respiration is an aerobic process. This NADH and FADH 2 are used in the production of ATP during the electron transport chain. (Fig.3). Oxygen accepts the electrons after they have passed through the electron transport chain and ATPase, the enzyme responsible for creating high-energy ATP molecules. Formulate an explanation for why the events of the electron transport chain constitute an aerobic process rather than an anaerobic process (like glycolysis). The early fermentation processes would have provided not only the ATP but also the reducing power (as NADH or NADPH) required for essential biosyntheses. Aerobic fermentation produces the six water molecules by one glucose molecule in the Krebs cycles; conversely, anaerobic fermentation does not produce the water molecules.
