This cell is permeable to Urea, but not permeable to sucrose. Intracellular impermeant molecules cannot cross the plasma membrane.  The bath solution is ‘infinite volume’.  Bath Solution: 250 mM Sucrose 250 mM Urea Is this solution Hypoosmotic, Isoosmotic, or Hyperosmotic? Immediately after this cell is placed in the bath will it swell, shrink, or remain the same? Fill in this table for equilibrium conditions for each ion. Consider solute movement ONLY. in (mM) out (mM) Intracellular impermeants Sucrose Urea        At equilibrium, will the cell swell, shrink, or remain the same volume? Is this solution hypotonic, isotonic, or hypertonic?
