- cell membrane structure
- phospholipids
- bilayer
- hydrophobic tail
- hydrophilic head
- phosphate group is polar and so is soluble
- flexible
- fluid mosaic model
- bilayer
- proteins
- scattered throughout the bilayer
- fluid mosaic model
- channel proteins
- allow large molecules to pass through
- carrier proteins
- allow large molecules to pass through
- carrier proteins
- receptor proteins
- detect chemicals released from other cells
- e.g. insulin binds to receptor proteins on liver cells which tell the cell to absorb glucose
- detect chemicals released from other cells
- some can move throughout, some are static
- mechanical support
- scattered throughout the bilayer
- glycoproteins
- proteins with a polysaccharide chain attached
- recognition sites
- important for lymphocytes and immune function
- receptors
- glycolipids
- lipids with polysaccharide chain attached
- recognition sites
- important for lymphocytes and immune function
- stabilise membrane
- glycoproteins
- proteins with a polysaccharide chain attached
- receptors
- glycoproteins
- cholesterol
- type of lipid
- make phospholipdsless fluid
- prevent leakage of water and ions
- binds to hydrophobic tails of phospholipids causing them to pack closer together
- phospholipids
