Cell identification via glycoproteins.

How do molecules move during passive transport?

From high to low concentration, without energy input.

What is Osmosis?

Water movement across a semipermeable membrane.

What are channel proteins?

Transmembrane proteins allowing specific ions/molecules to cross.
