"WebMany tissues also contain the malate-aspartate shuttle, which can also carry cytosolic NADH into the mitochondria. Cytosolic NADH is used to reduce oxaloacetate (OAA) to malate, which can cross the mitochondrial membrane. Once inside the mitochondria, malate can be oxidized to OAA to produce NADH.
