A newborn presents with weak suckling, frequent vomiting, and hypotonia. Blood and urine citrulline are very high. What metabolic process is disturbed?
- A. Cori cycle
- B. Gluconeogenesis
- C. Ornithine cycle
- D. Tricarboxylic acid cycle
- E. Glycolysis
Hint
Ask which metabolic pathway has citrulline as an intermediate, and which other toxic nitrogen-containing compound would back up behind a block in a newborn.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
