Transfer of electron from NADH to electron transport chain during glycolytic pathway. But electron doesn't cross the mitochondrial membrane that's why two system used for electron transport chain. In which system name is Malate Aspartate Shuttle.br /In malate Aspartate Shuttle movement of electron in the form of malate from cytoplasm to mitochondrial matrix.
