Anaerobic Respiration Anaerobic respiration is the process in which a glucose is split into two pyruvates and then transferred to lactic acid or ethyl alcohol depending on the environment, does not use oxygen Anaerobic respiration occurs in the cytoplasm, outside of the mitochondria Lactic Acid Fermentation: Occurs at the time of strenuous activity or exercise to make two additional ATP on top of regular aerobic respiration that produces 38 ATP - Takes place in muscles, or with food products such as yogurt, cheese Does not use oxygen because there is enough oxygen for aerobic respiration however oxygen is now being pumped to the heart so it is not available for anaerobic respiration.
