4. Create some drawings/models of membrane transport proteins. Blob models are fine but they should be annotated as instructed below. In your drawing include a model for a lipid bilayer clearly showing the polar and non-polar nature of the lipid components. The models of the proteins should include annotation/shading or other indication that indicates the types of amino acid functional groups you might expect to see in (a) the exterior of the protein in contact with the lipid bilayer, (b)...
