Cell Membrane

The ability to allow only certain molecules into or out of the cell.

• Semipermeability

• Permeability

What is the function of the transport and channel proteins of the cell membrane?

• allows large molecules to pass through the cell membrane

• allows small, non-polar molecules to pass through the cell membrane

• identifies the cell and allow for cell-to-cell communication

• stabilizes the fluidity of the cell membrane

What is the function of the phospholipid bilayer of the cell membrane?

• allows large molecules to pass through the cell membrane
