"Fluid" - Phospholipds are constantly moving. "Mosaic" - proteins are scattered.
1 of 15
Channel Protein
A protein that allows facilitated diffusion of charged particles.
2 of 15
Carrier Protein
A protein that allows facilitated diffusion of large molecules.
3 of 15
Co-Transport Protein
A type of carrier protein that binds to two molecules are the same time - used in active transport.
4 of 15
Glycoprotein
A protein that has a carbohydrate attached to it -
5 of 15
Glycolipid
A lipid that has a carbohydrate attached to it -
6 of 15
Cholestrol
A type of lipid present in cell membranes -
7 of 15
Simple Diffusion (Lipid Diffusion)
The net movement of molecules from an area of high to low concentration. (DOWN its concentration gradient)
8 of 15
Facilitated Diffusion
The net movement of molecules from an area of high to low concentration using a channel and/or carrier protein. (DOWN its concentration gradient)
9 of 15
Osmosis
The net movement of water molecules from an area of low to high water potential through a partially permeable membrane.
10 of 15
Water potential
The likelihood of water molecules to diffuse out of or into a solution.
11 of 15
Hypotonic Solution
High water potential of solutes. (Low concentration) so water moves INTO the cell via osmosis.
12 of 15
Isotonic Solution
Same water potential of solutes. (Same concentration) so no net movement of water.
13 of 15
Hypertonic Solution
Low water potential of solutes. (High concentration) so water move OUT of the cell via osmosis.
14 of 15
Active Transport
The movement of molecules/ions across a plasma membrane from a low to high concentration which requires energy in the form of ATP and a carrier protein.
