KROK 1 2014 – Question 2 · KROK (Medicine) · Biological Chemistry
Malaria is treated with structural analogs of vitamin B2 (riboflavin). These drugs disrupt the synthesis of the following enzymes in plasmodium:
- A. NAD-dependent dehydrogenase
- B. Aminotransferase
- C. Cytochrome oxidase
- D. FAD-dependent dehydrogenase
- E. Peptidase
Hint
Trace riboflavin to the coenzyme forms it gives rise to, then ask which class of enzymes in the parasite's redox reactions cannot work without them.
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.
