Which iron transporter helps regulate intestinal iron absorption and release?

Question

Quizplus · Accepted Answer

Ferroportin is an iron transporter that is located on the surface of various cells, including the intestinal cells lining the gut. It is responsible for releasing iron into circulation from dietary sources and plays a crucial role in regulating intestinal absorption and release of iron. Hephaestin is a copper-containing oxidase that helps in the oxidation of iron and its transport across the basolateral membrane of intestinal epithelial cells. Platelets are not involved in iron transport, while ferritin is an intracellular protein that stores iron, rather than regulating its absorption and release.
