How does aero and anaerobic respreastion differ

Aerobic involves the use of oxygen and Anaerobic doesnt i hope i helped

Anaerobic respiration is done in the absence of oxygen (“an” = not, “aero” = air or atmosphere). Sometime anaerobic respiration is referred to as fermentation. ... During ethanol fermentation, pyruvate from glucose metabolism is broken into ethanol and carbon dioxide.

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
