passive transport the movement of particles without the use of ATP energy
2 types of passive transport osmosis and diffusion
diffusion particles move from a higher concentration to a lower concentration
facilitated diffusion type of diffusion with the help of protein channels
osmosis type of facilitated diffusion of water through a selectively permeable membrane with the help of aquaporins
Hypotonic a solution of low solutes compared to the solvent
Hypertonic a solution of high solutes compared to the solvent
Isotonic a solution of the same solutes and solvents
Hypertonic solution water moves out of the cell
Hypotonic solution water moves into cell
Isotonic solution water will move in and out of cell
protein pump proteins used in active transport
active transport movement of materials across a memebrane with the use of ATP energy and protein pumps
aqauporin a protein pump in which only water molecules can pass through
ATP supplies energy to protein pumps during active transport
endocytosis the process of molecules entering the cell
exocytosis the process of molecules exiting the cell
