Cell Membrane - Coggle Diagram

- - - - Phosphate head
        
        Hydrophilic (Polar)
      - Glycerol backbone
      - Fatty acids tails
        
        Hydrophobic
        
        Long carbon chains
        
        Types
        
        Saturated
        
        Single-bonded
        
        Straight & easy-to-pack tightly
        
        Unsaturated
        
        Double-bonded
        
        Hard-to-pack & have bumps
    - - Has both hydrophobic and hydrophilic sections
  - - - Maintains cell membrane's fluidity
        
        Temperature = higher, cholesterols help decrease fluidity
        
        Temperature = lower, cholesterols help increase fluidity
      - Avoided phospholipids from being too closely packed
  - - - Cut through membrane
    - - Sit on cell membrane's wall or other proteins
    - - One that goes halfway through the membrane
      - One that is inside the hydrophobic region
    - - Tell the cell what's going on outside
      - Transport molecules in and out of cell
        
        Specified in transmembrane proteins
  - - - On the outer side of the membrane
        
        Stick out from proteins
        
        Glycoproteins
        
        Stick out from lipid wall
        
        Glycolipids
- - - - Area between the two fatty acids tails layers: hydrophobic region
- - - - Passive diffusion
  - - - Fast
    - - Slow
    - - Slow
    - - Can't
    - - Can't
