<prompt> Hepcidin acts on which receptor to inhibit the iron absorption?DMT-1FerroportinHephaestinTransferrin  <response>: Ans. b FerroportinRef: Ganongs Review of Medical Physiology 25th Ed; Page No- 486 Maximum iron absorption occurs in duodenum. Hepcidin is produced by liver. It represses the basolateral transport of iron into the blood. Generally, transport of dietary iron into the enterocytes through divalent Metal Transporter-1 DMT-1; some iron stored in ferritin; then excess iron transported out the enterocytes through basolateral named ferroportion 1. Hepcidin level is regulated by HFF gene Hepcidin is a crucial molecule in iron metabolism, linking body stores with intestinal iron absorption. Mutation of HFF gene -Hemochromatosis
