Hemoglobin synthesis. The hemoglobin begins to be produced during the proerythroblast stage of the RBC cycle. The synthesis takes place in the mitochondria and ribosome by a series of biochemical reactions. In the mitochondria, the synthesis of the heme portion of hemoglobin takes place.Here, heme synthesis begins with the condensation of glycine & succinyl-CoA to form Î´-aminolevulinic acid (ALA). disruption at any point in the synthesis of hemoglobin can result in the following disorders: 1  Iron deficiency anemia. 2  Lead poisoning. 3  Thalassemia. 4  Sideroblastic anemia.
