Liposome micelle are structure made in lab, not found in nature

Key functions:

  • Anatomical barrier
  • Regular ionic composition

lipid bilayer:

  • ensures polar molecules cannot cross
  • lipophilic molecules and gases can

dedicated transport mechanisms

# The cellular membrane potential

at rest permeable to K+ but not Na+

equilibrium potential

multiple ions?

# Goldman Hodgkin Katz equation

P: permeability

# Equivalent electrical circuit
