Can you please confrim for me, "Are cell membranes formed from protein?"

Well, its not the primary macromolecule in a membrane... there are proteins embedded, but there's another primary macromolecule I'd list first.

Do a little more digging/reading and try again.

We won't do homework for you, but we can talk to you about your attempts.

Yes they are part of membrane cell...

Cell membranes composition is primarily of proteins and lipids, especially phosphplipids. These lipids occur in 2 layers(phospholipid bilayer) At these sites is where we find the proteins embedded.
