where does haemoglobin synthesis occur?
Haemoglobin synthesis 65% of the Hb is synthesized in the erythroblasts, and 35% at the reticulocyte stage. Haem synthesis occurs largely in the mitochondria. Globin synthesis occurs in the polyribosomes.Although haem and globin synthesis occur separately within developing red cell precursors, their rates of synthesis are carefully coordinated to ensure optimal efficiency of Hb assembly.aemoglobin synthesis The main function of red cells is to carry O 2 to the tissues and to return carbon dioxide (CO 2) from tissues to the lungs. In order to achieve this gaseous exchange the red cells contain the specialized protein haemoglobin.
