Question

question 31 (mandatory) (1 point) iron is transported in circulation bound to which of the following? a) hemosiderin b) tibc c) ferritin d) transferrin

Explanation:

Iron in circulation is transported bound to transferrin. Transferrin is a plasma - protein that binds and carries iron through the bloodstream to cells that need it. Hemosiderin and ferritin are involved in iron storage, not transport in circulation. TIBC (Total Iron - Binding Capacity) is a measure related to iron - binding potential in the blood, not the molecule to which iron is bound for transport.

Answer:

d) Transferrin
