Which one is product of aerobic respiration

  • Malic acid 

  • Ethyl alcohol

  • Lactic acid

  • Pyruvic acid


C.

Lactic acid

If the breathing rate and blood flow cannot supply enough oxygen to your working muscles, the body turns to anaerobic respiration. This is the production of energy without the use of oxygen. This system works by producing lactic acid to facilitate energy production.
