Assume a living cell with 0.9% (w/w) of glucose solution (aqueous). This cell is immersed in another solution having equal mole fraction of glucose and water. (Consider the data upto first decimal place only) The cell will : (1) Shrink since solution is 0.5 % (w/o) (2) Shrink since solution is 0.45% (w/o) as a result of association of glucose molecules (due to hydrogen bonding) (3) Swell up since solution is 1% (w/o) (4) Show no change in volume since solution is 0.9% (w/o)

1. Shrink since solution is 0.5 % (w/o)
2. Shrink since solution is 0.45% (w/o) as a result of association of glucose molecules (due to hydrogen bonding)
3. Swell up since solution is 1% (w/o)
4. Show no change in volume since solution is 0.9% (w/o)

Correct answer: Shrink since solution is 0.45% (w/o) as a result of association of glucose molecules (due to hydrogen bonding)

Solution

The correct option indicates that the external solution has a lower effective concentration of glucose due to the association of glucose molecules, which reduces the number of free glucose molecules in solution. This results in a lower osmotic pressure compared to the cell's internal environment, causing water to move out of the cell and leading to cell shrinkage.
