assistant
The correct answer is  Ceruloplasmin:- Copper-containing ferroxidase. Oxidizes toxic ferrous iron to its non-toxic ferric iron in the serum. This facilitates the transpo of iron by transferrin. This is why aceruloplasminemia leads to hemochromatosis. - Hephaestin is also a copper-dependent ferroxidase that oxidizes ferrous iron to ferric. It works in cooperation with ferropoin in the cells.
