Is the inside of the cell isotonic, hypotonic, or hypertonic? What will eventually happen to the cell?
PART II. When cells are in the process of moving ions and other solutes around to change concentrations across their membrane, they always have to deal with water moving as well -osmosis! That means if a cell does not want water to move it needs to make sure to balanceoverall solute concentrations. Anytime there is a difference in overall concentration of solutes water will move. Consider the figure below when answering the following questions.
Assume it defines the starting conditions for an experiment with a cell in a solution. Sucrose = 1.0 MSucrose = 0.2 MNa+ = 2.0 MNat = 0.4 M7. (1 pt) Suppose there is a sodium channel in the cell membrane.What will be the new concentration of Nat outside the cell?
What will be the new concentration of Nat inside the cell?(1 pt) Why would the concentrations of sucrose NOT change?8. (1 pt) After the movement of sodium is the inside of the cell (circle one) Isotonic hypotonic hypertonic 9.(2 pts) Draw an arrow indicating the net movement of water after sodium has moved. If nothing else changes what will eventually happen to the cell?10. (1 pts) We don’t want that to happen to our cell! So what are we going to do to prevent that from happening (be very specific)? (cells are lazy, so they would go for the simplest, most energy efficient method.)
