Aerobic respiration requires oxygen; anaerobic respiration does not use oxygen.
Aerobic Respiration: Respiration that requires oxygen Anaerobic Respiration: respiration that does not use oxygen aerobic respiration is continuous. anaerobic respiration has no new subsrates from photosynthesis to continue. it is usually shorter and not as efficient.
It invoves in respiration. Specifically it is aerobic respiration
Anaerobic respiration does not require oxygen, while cellular respiration does. Anaerobic respiration produces less energy compared to cellular respiration.
