Until now you have only observed oxygen and carbon dioxide diffusing
through a cell membrane. The way those two molecules directly pass
through the cell membrane is actually quite uncommon. Most molecules are
unable to pass through the membrane, so some kind of hole must be made
to allow them to diffuse through. This is done using one or more
proteins to create a pore in the membrane that allows only specific
molecules or ions to pass through.
</p>
<p>
To the right is the model of such a pore. This one allows water to pass
through a cell membrane.

true
They allow only ions to pass through.
They allow most molecules to pass through.
They let anything that is the right size through.
They are specific to one kind of molecule.
