Anaerobic respiration Definition:
Anaerobic respiration is a process in which substances other than O2, such as nitrate ions (NO3-) or sulfate ions (SO4 2-), accept electrons at the "downhill" end of electron transport chains.

Anaerobic respiration Notes:
Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain like the aerobic respiration. In aerobes oxygen is used as final electron acceptor, however In anaerobes, other less-oxidizing substances such as sulphate (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. Therefore, generally speaking, anaerobic respiration is less efficient than aerobic.
