|
|
Plasma Membrane |
Active barrier seperating inra / extracellular fluid. Controls what leaves and enters cell. |
|
|
Fluid Mosaic Model |
Double layer of lipid molecules with protein molecules "plugged into" it. |
|
|
Hydrophilic Lipid |
Phosphate heads (water loving) are polar/charged |
|
|
Hydrophobic Lipids |
Fatty acid tails (water hating) are non polar |
|
|
Integral Proteins |
Firny inserted into cell membrane. Both hydrophobic/philic regions Transport proteins (channels, carriers) |
|
|
Peripheral Proteins |
Loosely attached to integral proteins Intracellular surface used for membrane support Function as enzymes, motor proteins for shape change during cell division and cell to cell connections |
|
|
Glycocalyx |
Sugars(carbs) sticking out of a cell surface. Cell recognition. |
