Cell Membrane Structure and Function Quiz

Cell Membrane Structure and Function

• The cell membrane primarily separates the interior of the cell from the outside environment.
• Channel proteins allow free movement of water, as well as selected ions or molecules through the cell membrane.
• Carrier proteins bind with specific molecules or ions for transportation through the cell membrane.
• The main composition of the cell membrane is a phospholipid bilayer.
• The hydrophobic tails of the phospholipid bilayer form a barrier against water molecules and water-soluble substances.
