Which of these proteins functions to store or transport iron?

A. ferritin, hemosiderin, and transferrin
B. ferritin
C. hemoglobin
D. transferrin
E. hemosiderin


Sagot :

Final answer:

Transferrin transports iron, ferritin serves as an intracellular iron-storage protein, and hemosiderin is also involved in iron storage.


Explanation:

Transferrin is the major iron transport protein in the blood that binds to ferric iron (Fe³+) for transportation. Once inside a cell, iron is stored in ferritin, an intracellular iron-storage protein in both eukaryotes and prokaryotes. Additionally, hemosiderin is another protein where iron can be stored at higher concentrations.
