Consist of a phosphate ion and two fatty acids chains, meaning that have a hydrophilic 'head' and a hydrophobic 'tail'
Phospholipid
1 of 8
The net movement of molecules/ions from a region of high concentration to a region of low concentration
Diffusion
2 of 8
The movement of molecules/ions through transmembrane channels and carriers along a concentration gradient
Facilitated diffusion
3 of 8
The passage of water from a region of high water potential to a region of low water potential across a selectively permeable membrane
Osmosis
4 of 8
The movement of molecules/ions into or out of a cell from a region of low concentration to a region of high concentration through the use of ATP and carrier proteins
Active transport
5 of 8
Sodium ions are actively removed from the cell/organelle whilst potassium ions are actively taken in from surroundings
Sodium-potassium pump
6 of 8
The transport if one substance coupled with another across a plasma membrane in the same direction, using the same protein carrier
