Glycolytic pathway is an anaerobic pathway and does not require oxygen essentially for conversion of glucose to pyruvate. However, glycolysis is categorized as aerobic or anaerobic depending upon the oxidation of NADH generated during glycolysis. WebGlycolysis is the first pathway used in the breakdown of glucose to extract energy. It was probably one of the earliest metabolic pathways to evolve and is used by nearly all of the organisms on earth.
