<prompt> The pathogenesis hypochromic anemia in lead poisoning is due to -Inhibition of enzymes involved in heme biosynthesisBinding of lead to transferrin, inhibiting the transpo of ironBinding of lead to cell membrane of erythroid precursorsBinding of lead to ferritin inhibiting their breakdown into hemosiderin  <response>: Ans. is a i.e., Inhibiton of enzymes involved in Heme biosynthesis o Lead interferes with the syntheiss of Heme by inhibiting the enzymes d Aminolevulinic acid dehydrase and Ferrochelatase. These two enzymes are involved in the synthesis of Heme.
