Biomembranes
Functions of the plasma membrane
Each closed compartment has two faces
The freeze fracture, freeze etch method
15.1 A pure phospholipid bilayer acts as a selectively permeable barrier
15.1 A model for passive diffusion of small hydrophobic molecules across a pure phospholipid bilayer
15.2 Overview of membrane transport proteins
15.2 Purified transport proteins can be studied in artificial bilayer membranes called liposomes
15.3 Uniporter-catalyzed transport
15.3 A comparison of the uptake rate of glucose by facilitated diffusion and passive diffusion
15.3 An example uniporter: GLUT1 transports glucose into most mammalian cells
15.4 Ionic gradients and an electric potential are maintained across the plasma membrane
15.4 The membrane potential in animal cells depends largely on K+ resting potential
