Which transport process is the main mechanism for the movement of most macromolecules by body cells?

Question

Quizplus · Accepted Answer

Receptor-mediated endocytosis is the main mechanism for the movement of most macromolecules by body cells. This process involves the binding of the macromolecule to a specific receptor on the cell surface, triggering the formation of a vesicle that internalizes the macromolecule into the cell. Other processes such as pinocytosis and phagocytosis may also play a role in the uptake of some macromolecules, but they are not as selective as receptor-mediated endocytosis. Secondary active transport is a mechanism for the movement of ions and other small molecules across the cell membrane, but it is not typically involved in the transport of macromolecules.
