1 Fluid mosaic model of cell membrane
Some Phosopholipids connected as a "phosolipid bi-layer" (see KBhBIO101StructuresOfLipids structure
- Charged head
- Nonpolar tail
So, head aligns and tail aligns, creating the basic structure of the membrane:

This is called the "fluid mosaic" model because there is nothing holding these together.
1.1 Stuff in the membrane
Cholesterol
Helps cells communicate
Proteans
- Makes sure the right molecules gets in/out
- Nonpolar Oxygen + CO2 could easily get through
- Polar and charged molecules can't get through, unless…
- Channeled proteins let specific polar particles through
Through various KBhBIO101CellMembraines protean transports, chemicals could get in and out of the cell.
