WebApr 28, 2024 · The following is an outline of the basic steps of the two types of endocytosis. Two types of endocytosis: phagocytosis and pinocytosis. Phagocytosis: A particle or substance binds to receptors on the cell’s surface, stimulating the release of pseudopodia (extensions of the plasma membrane filled with cytoplasm). WebPhagocytosis is the process by which a cell takes in particles such as bacteria, parasites, dead host cells, and cellular and foreign debris. It involves a chain of molecular processes. Phagocytosis occurs after the foreign body, a bacterial cell, for example, has bound to molecules called "receptors" that are on the surface of the phagocyte. ...
