Are integral proteins found either in the inner or the outer leaflet of the lipid bilayer of the cell membrane

Are carrier proteins that bind substrate for transport across the membrane or channel proteins that form aqueous pores through the membrane

Are channel proteins that bind the substrate that needs to be transported across the membrane

Are carrier proteins that make up the secretory vesicles used for extrusion of products from the Golgi apparatus
