KROK 1 2009 – Question 177 · KROK (Medicine) · Biological Chemistry
In clinical practice tuberculosis is treated with izoniazid preparation - that is an antivitamin able to penetrate into the tuberculosis bacillus. Tuberculostatic effect is induced by the interference with replication processes and oxidation-reduction reactions due to the buildup of pseudo-coenzyme:
- A. NAD
- B. FMN
- C. TDP
- D. FAD
- E. CoQ
Hint
Match the structure of the drug's isonicotinic acid part with the vitamin it imitates, then ask which redox coenzyme that vitamin is used to build.
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.
