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. a series of practices to avoid contamination. Water. In aerobic respiration, the final electron acceptor (i.e., the one having the most positive redox potential) at the end of the ETS is an oxygen molecule (O 2) that becomes reduced to water (H 2 O) by the final ETS carrier. Both of these processes occur during cell metabolism. In anaerobic respiration, other electron acceptors are used, such as sulfate. The cell lacks a sufficient amount of any appropriate, inorganic, final electron acceptor to carry out cellular respiration. Rather, an inorganic acceptor such as sulfate (SO42-), nitrate (NO3–), or sulfur (S) is used. The final electron acceptor in aerobic respiration is oxygen, according to McGraw Hill Education. These include nitrate ions, sulfate ions, or even carbon dioxide. Anaerobic respiration is a type of respiration where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors. What Is the Final Electron Acceptor in Aerobic Respiration. If that acceptor is oxygen, the process is considered aerobic respiration. NAD+. Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. This process is the most energy-efficient in organisms and results in the most ATP produced per molecule of glucose oxidized compared the anaerobic respiration. - Definition & Examples.

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. Cytoplasm. Fermentation occurs when an organic energy source is degraded and oxidized without the use of an exogenous electron acceptor; when the energy source is degraded and oxidized in the absence of this electronic acceptor, the process is known as respiration. What Are the Steps of Presidential Impeachment? Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. CHEMIOSMOSIS • As electrons move from one molecule to another in the chain, energy is released via a process called chemiosmosis . Chemo-trophic micro-organisms vary in terms of their electron acceptors and their energy sources. If aerobic respiration occurs, then ATP will be produced using the energy of the high-energy electrons carried by NADH or FADH 2 to the electron transport chain.
