And the malate can now move across a special antiported transport system found on the inner membrane of the mitochondria. And as the malate moves into the matrix of the mitochondria, an alpha ketoglutrate is exchanged for that malate and it moves into the intermembrane space and then the cytoplasm of that particular cell. So in step one, the NADH that is produced in glycolysis is used to reduce oxyloacetate into malate. 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.
