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
