• A

• B

• C

• D

Hydrophilic head portion of cell membrane?

• A

• B

• C

• D

What is D

• Phospholipid
• carrier protein
• cholesterol
• peripheral protein

What forms the channels (doors) and pumps in the phospholipid bilayer?

• Carbohydrates

• Proteins

• Hydrophilic heads

• Lipids

The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell
• Certain things can enter while others cannot
• The cell manually sorts through all materials
• Only certain cells can interact with the cell.
