• Regulate what is transported into and out of the cell

• Package materials

• Make proteins

Look at the diagram of a cross-section of a cell membrane below. The cell membrane controls movement of materials into and out of the cell. The following particles are moving from high concentration to low concentration and are using a carrier protein. How would you describe this type of movement across the membrane?

• simple osmosis

• active transport

• simple diffusion

• facilitated diffusion

• From side B to the side A.

• The purple molecules would not move.

Which of the following is a function of the cell membrane?

In the context of cell transport, what is the main difference between active transport and passive transport?

• Active transport requires energy, while passive transport does not.

• Passive transport requires energy, while active transport does not.

• Active transport can only move materials out of the cell, while passive transport can move materials in both directions.

• Passive transport can only move materials into the cell, while active transport can move materials in both directions.

Which of the following is NOT a component of the cell membrane?

• Phospholipids

• Ribosomes

• Proteins

• Cholesterol

Where will molecule X try to move to?

• Side A

• Side B

• Out of the box

• Stuck in the membrane

Based on these results, which statement correctly predicts what will happen to red blood cells when they are placed in a beaker containing a water solution in which the salt concentration is much higher than the salt concentration in the red blood cells?

• The red blood cells will absorb water and increase in size

• The red blood cells will lose water and decrease in size.

• The red blood cells will first absorb water, then lose water and maintain their normal size.

• The red blood cells will first lose water, then absorb water, and finally double in size.
