stleo019 Posted April 22, 2011 Share Posted April 22, 2011 1)Membrane lipids from 4.74*109 erythrocytes form a monolayer of 0.89 m2 in water. The surface area of an average erythrocyte is ~ 100 mm2. Show that the membrane is a bilayer. 2) How many moles of K+ will diffuse across the erythrocyte membrane in one minute under the following conditions:[K+]in = 100 mM [K+]out = 15 mM Surface Area of erythrocyte: 100 mm2 = 100*10-12 m2 Permeability P of K+ = 2.4*10-10 cm-sec-1 If the erythrocyte volume is 100 mm3, what percent of the internal K+ willl leak out in 1 minute?

Greippi Posted April 25, 2011 Share Posted April 25, 2011 What aspect of that do you need help with? It's simple maths. Link to comment Share on other sites More sharing options...
