What is the relationship between the transferrin receptor and ferritin when iron stores are low? A)The expression of transferrin receptor increase to maximize the uptake of iron from the blood into the cells,and the expression of ferritin decrease. B)The expression of both the transferrin receptor and ferritin increase,to promote the uptake of iron into the cells. C)The expression of transferrin receptor decrease and the expression of ferritin increase so iron remains in the cell. D)The expression of both the transferrin receptor and ferritin decrease to maximize the amount of iron circulating in the blood.

When iron stores are low, the body increases the expression of transferrin receptor to enhance iron uptake from the blood into cells, while decreasing the expression of ferritin to reduce iron storage, thus making more iron available for essential functions.
