And what that implies is the skeleton muscle cells will be able to get that oxygen and the oxygen will go around all the different types of skeleton muscle cells. And so to basically meet the high demand of ATP molecules, these skeleton muscles will essentially begin the process of glycolysis. They will increase the rate of glycolysis which produces ATP and Pyruvate molecules. Now Pyruvate under aerobic conditions will go into the mitochondria and the citric acid cycle will take place. And that will not only generate many more ATP molecules, but perhaps even more importantly, it will regenerate those NAD plus coenzymes that are essentially used up in step six of glycolysis. So remember, in glycolysis, in step six we essentially use up NAD plus coenzymes.
