Question

Why is anaerobic respiration energetically less efficient than aerobic respiration?


Anaerobes use less oxidizing substances like sulfate or nitrate during the electron transport chain so less energy is released per oxidized molecule.
Anaerobes use only oxygen during the electron transport chain, while aerobes use both oxygen and carbon dioxide which results in a more efficient process.
Anaerobes' terminal electron receptors have larger reduction potentials than O2 meaning that more energy is released per oxidized molecule.
The aerobic respiration process uses a respiratory electron t
