So in this shuttle process, the NADH is regenerated in the matrix of the mitochondria. So we saw that in the previous discussion when we discussed the glycerol three phosphate shuttle, we saw that a net result of 1.5 ATP molecules were produced from a single NADH that was NADH that was generated in the process of glycolysis. Now the question is, what is the net quantity of ATP molecules produced by this NADH molecule that is transported into the matrix of the mitochondria via the malade aspartate shuttle process? So once the NADH is actually formed within the matrix of the mitochondria, it goes on to complex one of the electron transport chain. And this is in contrast to the previous shuttle system that we discussed, the glycerol phosphate shuttle system, in which the NADH actually ends up the electrons on the NADH end up being transferred onto complex three. So here the NADH is basically we take the NADH that we form in the matrix and we essentially oxidize it into NAD plus.
