protein with a chain of carbohydrate molecules attached
glycoprotein

cell surface membrane
cell surface membrane
4 of 11
movement of molecules from an area of high concentration of that molecule to an area of low concentration; it may or may not be across a membrane; it does not involve metabolic energy
diffusion
5 of 11
movement of molecules from an area of high concentration to low concentration, across a partially permeable membrane via protein channels or carriers; it does not involve metabolic energy
facilitated diffusion
6 of 11
passage of water molecules down their water potential gradient across a partially permeable membrane
osmosis
7 of 11
measure of the tendency of water molecules to diffuse from ore region to another
water potential
8 of 11
the movement of substances against their concentration gradient (from low to high) across a cell membrane using ATP and protein carriers
active transport
9 of 11
bulk transport of molecules too large to pass through a cell membrane even via channel carrier proteins into a cell membrane
endocytosis
10 of 11
bulk transport of molecules too large to pass through a cell membrane even via channel or carrier proteins, out of a cell
exocytosis
