And what this does is it allows that cell to regenerate the NAD plus that is needed by glycolysis to actually continue glycolysis. And it also transfers the pair of electrons from the NADH onto that oxyloacetate to form the malate, so that once the malate moves into this matrix of the mitochondria, we can actually oxidize that malate back into oxyloacetate and reduce an NAD plus found in the matrix into NADH. And that NADH can be used by the electron transport chain, as we'll see in just a moment. So in step two, once we form the malate in the cytoplasm of our cell, the malate then moves into the intermembrane space via the outer membrane of the mitochondria. And then that malate enters the matrix of the mitochondria via a special antiporter transport protein in exchange for an alpha key to gluterate. And in step three, we actually take the high energy electrons on the malate that initially came from NADH, and we place them onto that NAD plus coenzyme to actually form the NADH.
