<prompt> Transferrin in the blood is saturated with iron normally by:35857215  <response>: Transpo of Fe2 into the enterocytes occurs divalent metal transpoer 1 DMT1. Some is stored in ferritin. A protein called hephaestin Hp is associated with ferropoin 1. It is not a transpoer itself, but it facilitates basolateral transpo. In the plasma, Fe2 is conveed to Fe3 and bound to the iron transpo protein transferrin. This protein has two iron-binding sites. Normally, transferrin is about 35 saturated with iron, and the normal plasma iron level is about 130 microgdL 23 mumolL in men and 110 micro gdL 19 mumolL in women.
