Membranes are made up of 2 molecules: 

  • Phospholipid, which forms the bulk of the membrane 
  • Proteins, that are scattered around the membrane 


  • Lipid molecule 
  • Made out of Gylcerol molecule awith a phosphate group and 2 fatty acid chains 
  • Phosphate group is hydrophillic (water loving)- hydrophillic heads 
  • Fatty acid groups are hydrophobic (water hating)- hydrophobic tails  
  • They form a phospholipid bilayer 
  • There is water inside and outside the cell
