Key Concepts

Receptor-Mediated Endocytosis

This is a specialized form of endocytosis in which a cell uses specific receptors on its surface to recognize and bind to targeted molecules. Once a molecule binds, it triggers the formation of a vesicle, often coated with proteins such as clathrin, allowing the cell to selectively internalize only those substances for which it has receptors.

Phagocytosis

Phagocytosis is a process by which cells, particularly specialized immune cells, engulf large particles, debris, or even entire microorganisms. Unlike receptor-mediated endocytosis, phagocytosis does not rely on specific receptor-ligand interactions for the uptake process and involves the extension of the cell membrane to form pseudopods that surround and internalize the target particle.
