WebThe Pathway of Gluconeogenesis. During starvation, alanine is transported from the muscle to the liver, where it is converted into pyruvate. As mentioned above, during fasting the pyruvate dehydrogenase complex is inhibited by the products of fatty acid oxidation. At the same time, acetyl CoA activates PC, thus converting pyruvate into ... Web1. Amino acids are an important substrate for gluconeogenesis during fasting. The following are the major gluconeogenic amino acid received by the liver a. Alanine b. Glycine c. Cysteine d. Leucine e. Valine 2.
