Transport: Movement Through the MembraneA. Cell Membrane is composed of?

protein channel

Carbohydrate chains Lipids

1. Function: Regulates what enters and leaves the

cell: semi-permeable membrane Provides protection and support Cell identification

Go to Section:

B. Transportation

1. Diffusion Movement of molecules from an area of high concentration to

area of low concentration Movement occurs without any ATP Eventually looking for equilibrium, or stability2. Passive Transport Movement of molecules across a membrane going along its

concentration gradient Concentration gradient:

the amount of molecules in a certain area where there is movement from a highly concentrated area to a low concentrated area

07_11Diffusion_A.html

3. Osmosis Diffusion of water through a semi-permeable membrane from

area of high concentration to low concentration Water will move across the membrane until equilibrium has

been reached4. Questions: Movement of Water

1. If high concentration of water molecules in the cell where will the water go?2. If there is a low concentration of water molecules, where will the molecules go?3. When equilibrium is reached is the concentration of the solution in the cell compared to outside of the cell different or the same?

C. Types of Solutions

Isotonic: The amount of solutes compared to the amount in a cell are equal to

the amount outside the cell

Hypertonic: The amount of solutes in the solution are high

Hypotonic: Amount of solutes in a solution are low

Answer the following:

1. What is the preferred solution for a red blood cell?

2. What will happen to a red blood cell if you place it in distilled water?

3. What will happen to an animal cell if it were placed in a salt water solution?

4. What is the preferred solution for a plant cell?

5. Why can a red blood cell not live in the same type of solution as a plant?

D. More Types of TransportA. Facilitated DiffusionIf a molecule is too large to pass through the membrane, it needs assistance via protein channel.

B. Active Transport Transport of material through the membrane with the use of ATP The molecules are going against the concentration gradient
