Card 14 / 47:
Why is receptor-mediated endocytosis said to be more selective than phagocytosis or pinocytosis?
Receptor-mediated endocytosis is more selective because the substances that are brought into the cell are the specific ligands that could bind to the receptors being endocytosed. Phagocytosis or pinocytosis, on the other hand, have no such receptor-ligand specificity, and bring in whatever materials happen to be close to the membrane when it is enveloped.
