Final answer:
Copper is a trace mineral that is necessary for the production of hemoglobin. It is a component of two proteins, hephaestin and ceruloplasmin, which help with the oxidation and transport of iron. Copper deficiency can affect the transport of iron for heme synthesis.
Step-by-step explanation:
Copper is a trace mineral that is necessary for the production of hemoglobin. Without copper, hemoglobin cannot be adequately produced. Copper is a component of two plasma proteins, hephaestin and ceruloplasmin, which enable the oxidation of iron and its transport to body cells. In a state of copper deficiency, the transport of iron for heme synthesis decreases.
