A final or terminal electron acceptor is a molecule that accepts electrons right at the end of a chain of electron transfer. Cellular respiration begins when electrons are transferred from NADH and FADH 2 —made in glycolysis, the transition reaction, and the Krebs cycle—through a series of chemical reactions to a final inorganic electron acceptor (either oxygen in aerobic respiration or non-oxygen inorganic molecules in anaerobic respiration). Different types of organisms use different types of final electron acceptors. Some obligate anaerobes use fermentation, while others use anaerobic respiration. The final acceptor of electrons in the electron transport chain during aerobic respiration is molecular oxygen although a variety of acceptors other than oxygen such as sulfate exist in anaerobic respiration. Different types of organisms use different categories of final electron acceptor which can be nitrate ions, sulfate ions, or carbon dioxide. What does it mean when there is no flag flying at the White House? The most common of final electron acceptors is molecular oxygen , O 2 , which combines with the spent electrons of cellular respiration , along with protons , to generate what is known as metabolic water . A final or terminal electron acceptor is a molecule that accepts electrons right at the end of a chain of electron transfer. Some examples of anaerobic respiration Use of nitrates as an electron acceptor Anaerobic respirers such as Bacillus and Pseudomonads are common soil inhabitants that will use nitrate (NO 3 ) as an electron acceptor. This can be seen in yeast fermentation, which gives alcohol as the final acceptor and does not break further for releasing energy. Some examples of anaerobic respiration Use of nitrates as an electron acceptor . 3. Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O 2).Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain. In aerobic respiration, the terminal electron acceptor is oxygen, which combines with two protons and the gained electrons (from the electron transport chain) to form water. The chemical reaction transfers energy from glucose to the cell. Sie können Ihre Einstellungen jederzeit ändern. Final Electron Acceptor thus is the final thing to accept an electron, particularly at the point where the organism or at least biochemical pathway is now done (finished) with the electron.

Chemo-trophic micro-organisms vary in terms of their electron acceptors and their energy sources. The main difference between fermentation and anaerobic respiration is the mechanism of each type of respiration. The final electron acceptor in aerobic respiration is oxygen.Without oxygen, aerobic respiration is not possible and the organism must revert to anaerobic respiration which produces much less ATP. Without oxygen, aerobic respiration is not possible and the organism must revert to anaerobic respiration which produces much less ATP. Fermentation : In fermentation there is no electron transport chain present energy is derived by converting glucose in lactic acid, ethanol etc. Instead, molecules such as sulfate (SO 4 2-), nitrate (NO 3 –), or sulfur (S) … Both aerobic and anaerobic bacteria need to have ETC to synthesize ATP. Anaerobic respiration is one such methods of extracting energy from organic materials using other chemicals viz. It can have several final electron acceptors, such as sulfate, nitrate, sulphur or fumarate. This method still incorporates the respiratory electron transport chain, but without using oxygen as the terminal electron acceptor. The final electron acceptor of the anaerobic respiration is not the molecular oxygen as in aerobic respiration.

Overview of Final Electron Acceptor The aerobic respiration starts with the transport of ions from NADH and FADH2 that takes place in the process of glycolysis, and the citric acid cycle through a cycle of mechanisms to a terminal acceptor of electrons. This process is commonly used by prokaryotes that have varying degrees of oxygen utilization: facultative anaerobes can metabolize aerobically or anaerobically, but obligate anaerobes anaerobically respire and require strict no-oxygen conditions. In anaerobic respiration, the citric acid cycle and the electron transport chain are also carried out. Fermentation : In fermentation there is no electron transport chain present energy is derived by converting glucose in lactic acid, ethanol etc. These can be ions such as sulfur, ferric, manganese (IV), cobalt (III), and Uranium (VI) and compounds such as fumarate, sulfate, nitrate or carbon dioxide. sulphate or nitrate compounds as the final electron acceptor in the process. Both of these processes occur during cell metabolism. In aerobic respiration, the final electron acceptor is an oxygen molecule, O 2.If aerobic respiration occurs, then approximately 38 molecules of ATP will be produced using the energy of the high-energy electrons carried by NADH or FADH 2 to the electron transport chain.
