_____ embedded in the cell membrane act as gates and transportation systems that allow selected substances to pass through the membrane.

Respuesta :

Protein complexes

Explanation:

There is a lipid bilayer in which the protein molecules are embedded. They do not exist as single elements of the lipid membrane in a form of glycoproteins or membrane proteins, they work as diffusing complexes within the membrane. They perform important functions for the cell; such as ion and metabolite transport, signaling, cell adhesion, and migration.
