14. A bаby bоy demоnstrаtes the fоllowing symptoms: hyperketotic hypoglycemiа, lactic acidosis, hyperammonemia, hypercitrullinuria, and hyperalaninemia. Doctors determine that she has a pyruvate carboxylase deficiency. They recommend treating with biotin and aspartate supplementation. (10 pts – 2 ea.) a) Hypoglycemia is reduced blood glucose. Explain how this deficiency results in hypoglycemia. b) Hyperketosis means there are abnormally high levels of ketone bodies in the blood. Explain how this enzyme deficiency results in hyperketosis. c) The girl has both lactic acidosis and hyperalaninemia, which is elevated levels of alanine in the blood. Choose ONE of these symptoms and explain how this enzyme deficiency causes it. d) Hypercitrullinuria is an elevated level of citrulline in the urine. Explain how this enzyme deficiency results in hypercitrullinuria.
