Quizplus · Accepted Answer

Iron acquisition by cells involves the expression of transferrin receptors on the cell surface, binding of transferrin (which carries iron) to these receptors, and endocytosis of the transferrin-transferrin receptor complex. The release of iron from transferrin within endosomes actually requires acidification, not alkalization, of the endosome. This acidic environment facilitates the release of iron from transferrin, allowing it to be utilized by the cell.
