Answer» Anaerobic respirationisrespirationusingelectron acceptorsother thanmolecular oxygen(O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.[1] Inaerobic organismsundergoing respiration, electrons are shuttled to anelectron transport chain, and the final electron acceptor is oxygen.Molecular oxygenis a highlyoxidizing agentand, therefore, is an excellent electron acceptor. Inanaerobes, other less-oxidizing substances such assulphate(SO42−),nitrate(NO3−),sulphur(S), orfumarateare used. These terminal electron acceptors have smallerreduction potentialsthan O2, meaning that less energy is released per oxidized molecule. Therefore, generally speaking, anaerobic respiration is less efficient than aerobic. |
