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 disposed of using atmospheric oxygen.
phosÂ·phoÂ·glycÂ·erÂ·ate kiÂ·nase. An enzyme catalyzing the formation of 3-phospho-d -glyceroyl phosphate and ADP from 3-phospho-d -glycerate and ATP; this enzyme is a part of the glycolytic pathway; a deficiency of phosphoglycerate kinase (an X-linked disorder) results in impaired glycolysis in most cells.hosÂ·phoÂ·glycÂ·erÂ·ate kiÂ·nase.
