WebbPinocytosis occurs through small narrow channels on the membrane. Plasma membrane surrounds the liquid molecules to pinch them off into the cell. Process In the process of pinocytosis, small liquid molecules get engulfed by themselves by attaching on the surface of the plasma membrane. WebbEndocytosis occurs by multiple mech-anisms that fall into two broad categories: “pinocytosis” (the up-take of fluid and solutes) and “phagocytosis” (the uptake of large particles) (1). Pinocytosis occurs in virtually all cells, whereas phagocytosis is typically restricted to specialized mammalian cells.
