description "Lectures 1-3"
Movement of intermembrane proteins
Only laterally (left/right)
Stiffens membranes and increases fluidity
Amphipathic structures that form lipid bilayers and micelles.
What can go through the plasma membrane?
Hydrophilic molecules; ions are kept out.
An antiport; 3Na+ for every 2K+
Equation for osmolarity
# of dissociated ions * concentration
"Magic number" for iso-/hypo-/hypertonic cells
Fick's Law (diffusion)
D is the diffusion coefficient; larger molecules have a larger one.
Vant Hoff's Law (osmosis)
RT represents the free energy due to temp.
Nernst Potentials (Na+, K+, Ca++)
Na+= +60 mV
K+= -90 mV
Ca++= +120 mV
