Question

Quizplus · Accepted Answer

Receptor-mediated endocytosis is the main mechanism for the movement of most macromolecules by body cells, as it involves specific receptors that bind to the macromolecules and enable their uptake into the cell. Phagocytosis and pinocytosis are less specific and typically involve the uptake of larger volumes of material. Secondary active transport is a mechanism for the transport of ions or small molecules, but is not typically used for the uptake of macromolecules.
