Glycolysis results in 2 pyruvates and 2 NADH , which are rich in energy and are used later to power ATP. Typically Oxygen is needed for cellular respiration but in glycolysis it is not necessary which makes it an Anaerobic process. In the absence of Oxygen, the pyruvates created through Glycolysis are rerouted through Fermentation. In the absence of Oxygen in order to keep Glycolysis going it will need NAD+, so fermentation frees up an NADH. The Krebs Cycle and the Electron Transport Chain are both aerobic processes that require oxygen.Unlike glycolysis, the Krebs cycle does not take place in the cytoplasm instead it occurs within the inner membrane of the mitochondria. The Krebs Cycle uses the Glycolysis byproducts, pyruvates, to create 2 ATPS per glucose molecule plus some energy. First one of the pyruvate is oxidized by combining with an oxygen. Remember pyruvates are rich in carbon! Now that 2 pyruvates are left, it creates COA, acetyl coenzyme A, which create another 2 molecules of NADH. Each pyruvate creates 3 NADH and 1 FADH per cycle and since pyruvates come from glucose and glucose through the process of glycolysis creates 2 pyruvates, then 6 NADH and 2 FADH are
