Cell membrane and transmodal transport mind map
Cell membrane structure and function
chemical composition of cell membrane
Lipids
Phospholipids
cholesterol
Glycolipids
protein
Function
carrier protein
receptor protein
connexin
How it binds to the lipid bilayer
intrinsic membrane protein
Single, multiple, multi-subunit
external membrane protein
non-covalent bonding
lipid anchored protein
Covalent bonds bind to lipid molecules
carbohydrate
glycoprotein
Glycolipids
biological properties of cell membranes
asymmetry
membrane lipids
Phospholipids and cholesterol are relatively asymmetric
Glycolipid absolute asymmetry
Different membranous organelles have different lipid compositions
Membrane Protein
membrane sugar
Only located on the non-cytoplasmic surface
fluidity
membrane lipids
1. Degree of saturation of fatty acid chain; 2. Length of fatty acid chain; 3. Cholesterol; 4. Ratio of lecithin and sphingomyelin; 5. Membrane protein; 6. Others (temperature, ph, etc.)
Membrane Protein
Controlled by the internal structure of the cell (microtubules in the cytoskeleton are fixed and microfilaments are pulled)
Main functions of cell membrane
1. Material barrier and permeability; 2. Organization and positioning; 3. Participation in transport; 4. Cell recognition; 5. Connection
cell membrane molecular structure model
lamellar structure model
Dark-light-dark three-layer structure
Liquid Mosaic Model
Advantages: Emphasis on membrane fluidity and asymmetry
Disadvantages: It cannot explain how a fluid cell membrane maintains membrane integrity and stability during movement.
lattice tessellation model
plate mosaic model
lipid raft model
Material transportation through mold
