KROK 1 2008 – Question 107 · KROK (Medicine) · Biological Chemistry
A 3 year old child with symptoms of stomatitis, gingivitis and dermatitis of open skin areas was delivered to a hospital. Examination revealed inherited disturbance of neutral amino acid transporting in the bowels. These symptoms were caused by the deficiency of the following vitamin:
- A. Pantothenic acid
- B. Vitamin A
- C. Niacin
- D. Biotin
- E. Cobalamin
Hint
An inherited failure to absorb neutral amino acids deprives the body of an essential amino acid that is also a precursor of a water-soluble vitamin; match the skin and mucosal signs in the child to the deficiency of that vitamin.
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.
