Two ATP molecules are 'spent' in the energy investment phase of glycolysis. Why is this energy necessary to begin the process of glucose catabolism? It is needed to prime the enzymes of glycolysis. Some energy must be invested to make glucose more reactive. It isn't; glucose contains 686 kcal/mole in its chemical bonds, so its catabolism is spontaneous. It is needed to generate the electron carrier NAD^(+).
