cell structure, function, and transport Flashcards
is used during active transport but not passive transport
energy
process by which a cell takes in material by forming a vacuole around it
endocytosis
particle movement from an area of higher concentration to an area of lower concentration
passive transport
process by which a cell expels wastes from a vacuole
exocytosis
a form of passive transport that uses transport proteins
facilitated diffusion
particle movement from an area of lower concentration to an area of higher concentration
active transport
transport protein that changes shape when a particle binds with it
carrier problem
the diffusion of water through a cell membrane
endocytosis
the movement of substances through the cell membrane without the use of cellular energy
passive transport
used to help substances enter or exit the cell membrane
transport protein
when energy is required to move materials through a cell membrane
active transport
a vacuole membrane fuses the cell membrane and the contents are released
exocytosis
the cell membrane forms around another substance, for example, how the amoeba gets its food
endocytosis
when the molecules move from areas of high concentration to areas of lower concentration
diffusion
causes a cell to swell
causes osmosis
hypotonic solution
