WebUnder normal conditions the gluconeogenesis occurs during starvation to supply glucose to the cells, especially the brain which is dependent on the glucose. Stress increases the hepatic glucose production by increasing the activities of key gluconeogenic enzymes viz. phosphoenol pyruvate carboxy kinase (PEPCK), pyruvate carboxylase, fructose 1 ... WebAccording to the model presented here, the high protein requirement of the domestic cat is the result of routing of amino acids into gluconeogenesis to supply the needs of the brain and other glucose-requiring tissues, resulting in oxidation of amino acid in excess of the rate predicted for a non-hypercarnivorous mammal of the same size.
