Question

osmotic flow...please help The value of L_P for the red blood cell is about 1.8 Times 10^-11 cm^3 dyne^-1 s^-1. Its surface area is about 1.35 Times 10^-6 cm^2 (Solomon, Methods in Enzymology, pp. 192-222, 1989). What is the initial osmotic flow if the osmolarity inside is initially 300 mOs M and the osmolarity outside is 275 mOs M? (Assume sigma = 1.0 for all solutes.) If the volume of the cell is 100 Times 10^-12 cm^3, how long would it take to double its volume provided that the osmotic pressure and area of the membrane and L_P did not change? In the case described, how much water would be required to enter the cell to equilibrate the osmotic pressure between inside and outside? Assume that the outside bath is essentially infinite so that its osmotic pressure is kept constant.
