Assume that the interior and exterior of the lipid vesicle are osmotically matched, such that the osmotic pressure across the membrane is zero. (20 total) A. If the partition coefficient, k, is 0.0015 and the viscosity, η , is 0.001 N- s/m2, calculate the steady state flow rate of glucose across the membr...
