Question

Quizplus · Accepted Answer

Iron ions and cholesterol are brought into the cell by receptor-mediated pinocytosis, where the molecules bind to receptors on the cell surface and are then internalized in vesicles. Pinocytosis and phagocytosis are not specific enough to target these particular molecules, and bulk transport refers to the movement of larger substances such as proteins rather than iron ions or cholesterol.
