WebAnaerobic glycolysis is the transformation of glucose to lactate when limited amounts of oxygen (O 2) are available. [1] Anaerobic glycolysis is only an effective means of energy production during short, intense exercise, [1] providing energy for a period ranging from 10 seconds to 2 minutes. This is much faster than aerobic metabolism. [2] http://thiamine.dnr.cornell.edu/Thiamine_biochemistry.html
