Reference no: EM13534575

You are a doctor treating a patient who suffers from severehypoglycemia after prolonged (>24 hr.) fasting. Glucose is converted to lactatenormally in the patient’s liver. You administer glucogon and find that bloodglucose increases normally (the patient was in the well-fed state prior to thistest). The patient’s liver shows normal activities of pyruvate carboxylase and PEPcarboxykinase. Which enzyme may show a genetic defect that accounts for these findings?Briefly explain your reasoning.

Beriberi is caused by a deficiency of thiamine in the diet : Beriberi is caused by a deficiency of thiamine in the diet. Severeberiberi causes an increase in pyruvate concentrations in blood and urine. Explain this observation.
Glycogen by converting fat into glucose via oxaloacetate : Fats are usually degraded to acetyl CoA, which enters the TCAcycle. Glucose can be synthesized from oxaloacetate, a TCA cycle intermediate, bygluconeogenesis. After exercise, glycogen stores are depleted and must be restoredby eating carbohydrate.
