Anerobic glycolysis

Anerobic glycolysis is the transformation of glucose to lactate when limited amounts of oxygen (O₂) are available. This is only an effective means of energy during short, intense exercise, providing energy for 30 seconds to 2 minutes. It replenishes very quickly over this period and produces 2 ATP per glucose for about 5% of glucose's energy potential. See aerobic glycolysis[?] for longer, low intensity energy.
