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
