"Web28 apr. 2024 · 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). Pseudopodia surround the object until their membranes fuse, forming a phagocytic vesicle. " - Ion pumps and phagocytosis

WebActive transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes.
