Introduction
Anaerobic respiration is the form of respiration that does not use oxygen.
Organisms can make ATP without oxygen through the process of fermentation, the process of releasing energy from food molecules by producing ATP in the absence of oxygen. The two forms of fermentation are lactic acid fermentation and alcoholic fermentation.
Lactic acid fermentation produces lactic acid and regenerates NAD+ to allow glycolysis to continue. When your body cannot get enough oxygen, such as during rapid exercise, lactic acid is produced in your muscles because without enough oxygen the body cannot produce ATP. So, the muscles in your body will rapidly produce ATP through lactic acid fermemtation.
Alcoholic fermentation is used by yeast and a few other microorganisms. It forms ethyl alcohol and carbon dioxide as wastes, as well as NAD+.
