The pathogenesis of hypochromic anemia in lead poisoning is due to -
High-Yield Explanation
Iron should be combined with protoporphyrin to synthesize Heme. To synthesize protoporphyrin and combine it with iron, enzymes like ALA synthase, ALA dehydratase & Ferrochelatase are required. Lead inhibits heme synthesis by inhibiting enzymes ALA dehydratase & Ferrochelatase resulting in microcytic hypochromic anemia.
