Sagot :
The type of cells of ourselves and the lab partner will differ along with the mechanism.
a. Potassium will first move out of the cell using the mechanism of simple diffusion.
b. In this context Glucose will move into the cell by the mechanism of facilitated diffusion.
c. The solution here will be in hypotonic condition.
d. Water will flow into the cell because of the concentration level.
e. The cell will start expanding and probably lyse when the maximum limit is reached.
- A substance starts diffusing when it moves from a region of high concentration to a region of lower concentration. Diffusion mainly occurs in liquids and gases in which the particles collide randomly and spread out.
- Simple diffusion, osmosis, and facilitated diffusion are basically the three types of diffusion.
(i) Simple diffusion takes place when ions or molecules diffuse from a region of high concentration to an area of low concentration.
(ii) Water molecules move during the osmosis process. Through a semi-permeable barrier, they travel from an area of low solute concentration to a region of high solute concentration.
(iii) The flow of hydrophilic molecules or ions over the plasma membrane is known as facilitated diffusion. The distinction is that transport proteins enhance diffusion (i.e. carrier proteins or pore proteins).
- All three types of diffusion are passive modes of transport, hence they are non-energetic.
Your lab partner is an exchange student from Pluto. You are investigating cell transport methods, so you decide to use one of your partner's cells. Surprisingly, you notice that her cell contains some of the same substances as our cells. You quantify the concentration of these substances and determine that the cell contains 5% glucose and 0.3% potassium. The cell is placed in a solution containing 20% glucose and 0.1% potassium. The plasma membrane of this cell is similar to ours. It is permeable to potassium but not to glucose. That is, only potassium can cross the plasma membrane without using transporters. Use this information to answer the following questions.
a. Will potassium move into the cell or out of the cell? Which transport mechanism will be involved?
b. Will glucose tend to move into or out of the cell? What will happen to glucose movement through the plasma membrane as the number of glucose transporters decreases?
c. You place the cell in a new solution to study the process of osmosis. You know that sodium does not move across the alien cell membrane. You also know that the concentration of the intracellular fluid is equivalent to 5% sodium. The new solution contains 1% sodium. Is the 1% sodium solution hypertonic, isotonic, or hypotonic?
d. Will water flow into the cell or out of the cell?
e. What will be the effect of the water movement on the cell?
