Question 3 of 5
Hereditary methaemoglobinaemia is most commonly due to deficiency of which red cell enzyme?
Correct Answer: A
Rationale: Hereditary methemoglobinemia is most commonly due to cytochrome b5 reductase deficiency (Choice A), impairing reduction of methemoglobin to hemoglobin, causing cyanosis. Glutathione peroxidase (Choice B) protects against oxidative stress, not methemoglobin. Heme oxygenase (Choice C) degrades heme, unrelated here. Methylenetetrahydrofolate reductase (Choice D) affects folate metabolism. Cytochrome b5 reductase is the key enzyme.
