In Glycolysis, each molecule of glucose yields 2 molecules of pyruvate, 2 molecules of NADH, and a net of 2 molecules of ATP.
Energy in the form of ATP (adenosine tri-phosphate).Glycolysis takes 1 molecule of glucose and turns it into energy the body can use. Glycolysis is not dependent on Oxygen so Oxygen concentrations don't effect glycolysis.
