View Full Version : I-Membrane Structure and Function


  1. 1- Membranes are fluid mosaics of lipids and proteins with many functions
  2. 2- The spontaneous formation of membranes a critical step in the origin of life
  3. 3- Passive transport is diffusion across a membrane with no energy investment
  4. 4- Osmosis is the diffusion of water across a membrane
  5. 5- Water balance between cells and their surroundings is crucial to organisms
  6. 6- Transport proteins can facilitate diffusion across membranes
  7. 7- Research on another membrane protein led to the discovery of aquaporins
  8. 8- Cells expend energy in the active transport of a solute
  9. 9- Exocytosis and endocytosis transport large molecules across membranes
