A patient was seen by a gastrointestinal specialist and diagnosed with a glycogen storage disease. A liver biopsy showed that the patient was producing very little glycogen, the molecules were relatively small, and they only had a(1,4) glycosidic linkages. Blood and liver glucose concentrations were within normal ranges. What enzyme is likely affected in this disease?
a. glycogen synthase
b. glycogen phosphorylate
c. branching enzyme
d. debranching enzyme
e. hexokinase
The answer is the 'debranching enzyme'.
Explanation: People with glycogen storage disease don’t have enough of an enzyme called the debranching enzyme, which helps in breaking down the glycogen. The glycogen can’t fully break down. It collects in the liver and in muscle tissues. The symptoms include a swollen belly, delayed growth, and weak muscles.

A baby is brought to the doctor by his parents after
experiencing irritability and seizures when he sleeps through the
night. Tests showed fasting hypoglycemia (low blood glucose
concentration), increased serum lipid levels, elevated blood
lactate after glucose administration, and elevated uric acid. The
child also had an enlarged abdomen. Glycogen levels were increased
in hepatocytes. (Assume the glycogen is of normal structure.)
The patient has a glycogen storage disease. Which enzyme of
glycogen metabolism is affected?
Answer the question...
Type 0 glycogen storage disease (GSD 0) is affecting glycogen synthase in the liver by slowing down glycogenesis. In general, GSD 0 develops in the early childhood causing symptoms, such as fatigue, vomiting, and looking pale. The medical doctor recommends frequent meals/snacks every 3-4 hours, keto diet based on fat rich meal and avoid fasting. Please explain why this treatment could be efficient for GSD 0. State your answer in full sentence related to the glucose concentration in blood plasma.
The patient was a 2 year old boy who presented with fasting hypoglycemia and acidosis. The liver was enlarged three-fold and kidneys two-fold. Hypoglycemia responded to oral doses of glucose but not to administered glucagon or epinephrine. During hypoglycemic episodes, lactic acid in the blood increased almost 10-fold higher than normal. Unlike the response in normal individuals, administration of oral galactose did not increase blood glucose concentrations but blood lactate levels were increased. Urine contained high levels of lactate. A...
