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. In this process, specific receptors on the cell surface recognize and bind to their ligands, which are usually macromolecules. The receptor-ligand complex is then internalized into the cell by invagination of the membrane, forming a vesicle. This process is highly regulated and allows cells to take up specific macromolecules, such as proteins and lipids, from the extracellular fluid.
