<P> Glycolysis is an oxygen independent metabolic pathway , meaning that it does not use molecular oxygen ( i.e. atmospheric oxygen ) for any of its reactions . However the products of glycolysis ( pyruvate and NADH + H ) are sometimes metabolized using atmospheric oxygen . When molecular oxygen is used for the metabolism of the products of glycolysis the process is usually referred to as aerobic , whereas if no oxygen is used the process is said to be anaerobic . Thus , glycolysis occurs , with variations , in nearly all organisms , both aerobic and anaerobic . The wide occurrence of glycolysis indicates that it is one of the most ancient metabolic pathways . Indeed , the reactions that constitute glycolysis and its parallel pathway , the pentose phosphate pathway , occur metal - catalyzed under the oxygen - free conditions of the Archean oceans , also in the absence of enzymes . Glycolysis could thus have originated from chemical constraints of the prebiotic world . </P>
