what is endocytosis? This is the process by which material move into the cell
what are the three types of endocytosis? phagocytosis, pinocytosis, and receptor-mediated endocytosis
what is phagocytosis? This is the process by which the cell's plasma membrane surrounds a macromolecule or entire cell from an extracellular environment and buds off to form a food vacuole or phagosome
what is another name of food vacuole? phagosome
what happens to the newly formed vacuole?, they fuse with a lysosome whose hydrolytic enzyme digest it
phagocytosis must fuse with _______ to digest imported materials lysosomes
what is pinocytosis? this is the process where the cell engulfs drops of fluid by pinching in and forming vesicles that are smaller than the phagosomes formed during phagocytosis
Is pinocytosis selective in the solutes it takes in? No, the process is non specific meaning that it takes in whatever solutes are dissolves in the liquid it envelopes
_________ is the process of "cellular drinking" pinocytosis
what is Receptor-mediated endocytosis? it is a process of importing materials into the cells
Is Receptor-mediated endocytosis selective in the solutes it takes in? Yes, it is a selective process
How is Receptor-mediated endocytosis specificity mediated? it is mediated by receptor proteins that are located on coated pits
mammalian cells use _______ to import cholesterol Receptor-mediated endocytosis
