Hepatocytes process and repurpose many metabolic waste products in addition to lactate from myocytes and erythrocytes. One prominent example is that many tissues, including muscle, produce the amino acid alanine as a waste product. Alanine can be converted into pyruvate in a single-step chemical reaction in hepatocytes. Which of the following are the most likely uses for the carbon backbones in alanine imported by the liver in this way? (select two answers). a) synthesis of glucose in gluconeogenesis for energy generation in the liver b) synthesis of glucose in gluconeogenesis for export from the liver c) catabolism into a-keto acids for energy generation in the liver d) catabolism into a-keto acids for export from the liver e) anabolism into fatty acids for energy generation in the liver f) anabolism into fatty acids for energy storage in the liver
