Homework Answers
hypertonic
because both NaCl and glucose act as a solute.
- less concentration of water outside then inside of the cell
- more solute outside then inside the cell
water move out and cell become shrink.

Imagine an artificial cell submerged in a beaker of water. There is an equal concentration of NaCl on either side of the cell membrane. The membrane is permeable to water. It also contains an artificial NaCl pump which can pump NaCl from inside the cell when power is connected (when the pump is off, the membrane is impermeable to NaCl). The pump is turned on and 50% of the NaCl in the cell moves to outside the cell. What happens?...
