The Glycolytic pathway describes the oxidation of glucose to pyruvate with the generation of ATP and NADH.
Glycolytic breakdown of glucose is the sole source of metabolic energy in some mammalian tissues and cells.
Glycolysis is a universal pathway; present in all organisms: from yeast to mammals.
Anaerobic microorganisms are entirely dependent on glycolysis.
It is also called as the Embden-Meyerhof Pathway.
It occurs in cytoplasm.
Glycolysis consists of series of 10 enzyme catalyzed reactions which are divided into two phases.
 1.Energy Investment Phase- in which 2 ATP forms 2 ADP and occurs from step 1 to 5.
2.Energy Payoff phase- in which 4 ADP forms 4 ATP, 2 NAD forms 2 NADH and occurs from step 6 to 10.
