Rzqust [24]
<h2>The given statement is true</h2>

Explanation:

Iron absorption occurs in the duodenum and upper jejunum of small intestine

  • At physiological pH ferrous iron is rapidly oxidized to the insoluble ferric form
  • Gastric acid lowers the pH in the duodenum which enhances the solubility and uptake of ferric iron
  • Once iron gets inside the enterocyte it can be stored as ferritin;Ferritin is a hollow spherical protein which helps in storage and regulation of iron levels within the body
  • Ferritin molecule have ferroxidase activity which helps in the mobility of Fe2+ out of the enterocyte by ferroportin
  • Transferrin is the major iron transport protein which transports iron through blood
  • Fe3+ binds to transferrin so Fe2+ transported through ferroportin must be oxidized to Fe3+
  • Fe2+ needs to be oxidized first so that it can be transported through ferroportin
  • Once iron gets inside the cell it can be used for various cellular processes
