A U-shaped tube has equal amounts of two solutions in it , separated by a membrane that is permeable to water and glucose, but not sucrose. Side A, on the left, has a solution of 10% sucrose and 20% glucose. Side B, on the right, has a solution of 20% sucrose and 10% glucose. Will there be a net movement of any substances across the membrane? If so, which? Will one side end up with more solution than the other? If so, which side?
