Exercise 24

Consider a U-shaped tube (as illustrated in Box 2.6) in which the arms of the U-tube are separated by a membrane that is permeable to water and glucose but not sucrose. The left side (side A) is filled with a solution of 2.0 M sucrose and 1.0 M glucose. The right side (side B) is filled with 1.0 M sucrose and 2.0 M glucose.
a. What changes would you observe, as the system moves toward equilib- rium?
b. During the period from initial filling to equilibrium, which molecule(s) will show net movement through the membrane?
