Correct Answer: Apoferritin
Description: (Ferritin):FERRITIN - is the storage protein of iron and found in blood liver, spleen, bone marrow and intestine (mucosal cells) The maximum iron content of ferritin on weight basis is around 25%.HEMOSIDERIN - is another iron storage protein which can hold about 35% of iron by weight. Hemosiderin accumulates in the body (Spleen, liver) when the supply of iron is in excess of body demands.Major function of Transferrin is transport of iron to RE cells, bone marrow to reach the immature red blood cells. Transferrin is internalized by receptor mediated endocytosis within the target cells, iron is released and apotransferrin is recycled to form new transferring molecules.
