Fluid Mosaic Model
Theory of cell membrane structure with proteins embedded in a sea of phospholipids
1 of 11
Glycolipid
Lipid/Phospholipid with a chain of carbohydrate molecules attached
2 of 11
Glycoprotein
Protein with chain of carbohydrate molecules attached
3 of 11
Plasma Membrane
Cell surface membrane
4 of 11
Diffusion
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
5 of 11
Facilitated Diffusion
Movement of molecules from an area of high concentration , acorss a partially permeable membrane via protein channels or carriers; it does not involve metabolic energy
6 of 11
Osmosis
Passage of water molecules down their water potential gradient, across a partially permeable membrane
7 of 11
Water Potential
Measure of the tendency of water molecules to diffuse from one region to another
8 of 11
Active Transport
The movement of substances agaisnt their concentration gradient across a cell membrane, using ATP and protein carriers
9 of 11
Endocytosis
Bulk transport of molecules, too large to pass through a cell membrane even via channel or carrier proteins, into a cell
10 of 11
Exocytosis
Bulk transport of molecules too large to pass through cell membrane even via channel or carrier proteins, out of a cell
