If the exercise lasts longer than 10 seconds the body switches to glycogen which is stored in liver and muscles. Glucose 6 phosphate Converted to before it is broken down to form Pyruvate Phosphofructokinase (PFK) and Glycogen This is done by Phosphorylate (GP) of 2 molecules of ATP. This system produces a net gain Lactic acid via lactate In the absence of oxygen pyruvate is converted to Dehydrogenase
