Mercury is toxic because it_____________?
Correct answer: B. Binds to sulfhydryl groups
- A. Complexes with hemoglobinto form methemoglobin
- B. Binds to sulfhydryl groups
- C. Inhibits anaerobic glycolysis
- D. Inhibits hemoglobin synthesis, producing anemia
Explanation
Mercury is toxic mainly because it binds to sulfhydryl groups on enzymes and proteins, disrupting cellular metabolism. Its toxicity is therefore not primarily due to methemoglobin formation or inhibition of anaerobic glycolysis.
