Von Gierke’s disease is a rare genetic disorder that results in a deficiency of glucose-6-phosphatase. Symptoms ketoacidosis, a buildup of glycogen in the liver, and lactate buildup. Why does this glycogen storage disease not affect the brain?
a) The brain is able to still perform glycolysis effectively
b) None of the above
c) In the event of hypoglycemia, the brain is able to utilize other sources of energy to produce ATP
d) The brain is able to metabolize lactate, which is present in high concetrations.
a) What is the reason for the non-oxidative phase of the pentose phosphate pathway?b) Which compound is converted into which compound in the step where sequential dehydration and hydration reactions occur in the citric acid cycle?c) Why is ammonia released in some tissues carried by binding to other molecules in the blood?
