The gut controls the entry of ingested iron in the body
by:
A. Regulating the availability of apoferritin
which acts as the carrier of iron across the
mucosal cell
B. Regulating the turnover of apoferritin-ferritin
interconversion in the mucosal cell
C. Complexing excess iron to form ferritin which
remains stored in the mucosal cell and is
shed off
D. Regulating the number of transferrin receptors on the mucosal cell
