the activities of some enzymes involved in both the utilization of glucose ( pyruvate kinase , atp citrate lyase , nadp-specific malate dehydrogenase , glucose 6-phosphate dehydrogenase , 6-phosphogluconate dehydrogenase and nadp-specific isocitrate dehydrogenase , all present in the supernatant fraction of liver homogenates ) and the formation of glucose by gluconeogenesis ( glucose 6-phosphatase in the whole homogenate and fructose 1,6-diphosphatase , phosphopyruvate carboxylase , nad-specific malate dehydrogenase and fumarase in the supernatant fraction ) have been determined in rat liver around birth and in the postnatal period until the end of weaning .
