By lowering the activation energy of the reaction
Answer: The solution was hypertonic
Explanation: The reason for this is the fact that the cell shriveled up. The shriveling was caused by water moving out of the cell. This movement is likely caused by a disbalance in solutes between the cell and the surrounding, with the surrounding containing a higher concentration of solutes. Diffusion tries to balance this by moving water out of the cell, thus increasing the concentration inside and reducing the concentration outside.
