KROK 1 2021 – Question 4 · KROK (Medicine) · Biological Chemistry
Patients with B₁₂-deficiency anemia develop degenerative processes in the posterior and lateral columns of the spinal cord (funicular myelosis). In this case, the damage to the axons is caused by the disturbed formation of:
- A. Myelin
- B. Noradrenaline
- C. Acetylcholine
- D. Dopamine
- E. Serotonin
Hint
Vitamin B₁₂ is a cofactor in reactions of fatty-acid and methyl-group metabolism; think about which component of the long spinal tracts is built and maintained by such reactions.
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.
