Theory of cell membrane structure with proteins embedded in a sea of phospholipids
1 of 10
Glycolipid
lipid/phospholipid with a chain of carbohydrate molecules attached.
2 of 10
Glycoprotein
Protein with a chain of carbohydrate molecules attached.
3 of 10
Plasma membrane
Cell surface membrane.
4 of 10
Diffusion
Movement of molecules from an area of high concentration of that molecule to an area of low concentration.
5 of 10
Facilitated diffusion
Movement of molecules from an area of high concentration of that molecule to an area of low concentration, across a partially permeable membrane via protein channels or carriers.
6 of 10
Osmosis
Passage of water molecules down their water potential gradient across a partially permeable membrane.
7 of 10
Water potential
Measure of the tendency of water molecule to diffuse from one region to another.
8 of 10
Active transport
Movement of substances from low to high concentration of that substance across a cell membrane, using ATP and protein carriers.
9 of 10
Endocytosis
Bulk transport of molecules, too large to pass through a cell membrane even via channel or carrier protein, out of a cell.
