MM less than 10 42mol (uooo0+2 mo.s +.0.15 ic 00 mls 500MIS А "A" and "B" are 2 compartments separated by a lipid based membrane operating like a cell membrane. Suppose that in the membrane there are pores or channels of various sorts: -one allows particles through regardless of their charge if the molecular weight is less than 40 one works by facilitated diffusion to transport glucose -one allows passage of cations medium sized (up to M.W. 2000), but blocks anions. At the start of the experiment, both compartments are 2 filled with distilled water (500 mls each side). To side A, we add 2 mol of albumin (MW> 60,000) To side B, we add 2 mol of the salt NaCI, 1 mol glucose, 0.25 mol cholesterol and 0.25 mol bicarbonate ions (H€O3) The system is gently stirred for the duration of the experiment. The system is allowed to "shift around" until all the solutes have reached their equilibrium.

Question

I am confused on the anions and cations portion. I dont understand how you are supposed to know what substance would be able to pass through the membrane with cations or not.
