Anaerobic respiration is a form of respiration using electron acceptors other than oxygen. Although oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain; it is respiration without oxygen.[1]
In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is a highly oxidizing agent and, therefore, is an excellent acceptor. In anaerobes, other less-oxidizing substances such as sulfate (SO42−), nitrate (NO3−), sulphur (S), or fumarate are used. These terminal electron acceptors have smaller reduction potentials than O2, meaning that less energy is released per oxidized molecule. Anaerobic respiration is, therefore, in general energetically less efficient than aerobic respiration.
Anaerobic respiration is a process of release of O₂ and uses glucose(C₆H₁₂O₆).It produces low energy in absence of O₂.This type of respiration is helpful in tissues with a great demand for energy such as working muscles,where there is not sufficient O₂ to produce all the energy required by using aerobic respiration alone.Anaerobic respiration is usually used in higher organisms where it occurs in the animal muscles, roots of some water-logged plants and in massive tissues as an additional mode of respiration.If there is a lack of O₂, lactic acid(C₃H₆O₃) fermentation is the type of anaerobic process that humans undergo.
