Malate can be transferred into the cytosol and interconverted in one enzymatic step to produce [oxaloacetate/glucose/PEP/pyruvate] for use in the pathway of [glycolysis/gluconeogenesis]. A product of the urea cycle, derived from aspartate, can also be converted to malate in one enzymatic step and shuttled into the mitochondria so that the urea cycle product can be used in [fatty acid synthesis/the citric acid cycle/β-oxidation]. The amino group from aspartate can be transferred to [oxalacetate/malate/fumarate/pyruvate/a- ketoglutarate] to form glutamate, which is then transported into the mitochondria. In fact many amino acids are transaminated in this way to form glutamate in the cytosol. In this way, incoming amino acids from the bloodstream can be shuttled into the liver mitochondria as glutamate for conversion by glutamate dehydrogenase to [glutamate/a-ketoglutarate…arrow_forward
