Question

select all of the following that are functions of membrane proteins. check all that apply transport chemicals into and out of cell form plant cell wall provide binding site for cholesterol serve as recognition molecules anchor cell membrane to cytoskeleton

Explanation:

Membrane proteins can act as transporters for chemicals, serve as recognition molecules (e.g., for cell - cell recognition), and anchor the cell membrane to the cytoskeleton. Plant cell walls are mainly composed of cellulose and other polysaccharides, not membrane proteins. While cholesterol interacts with the lipid - bilayer of the membrane, membrane proteins are not mainly for providing a binding site for cholesterol.

Answer:

transport chemicals into and out of cell
serve as recognition molecules
anchor cell membrane to cytoskeleton
