The plasma membrane is composed of a phospholipid bilayer with embedded proteins. what is one of the functions of the embedded proteins? a. protecting the cell from physical harm b. defining the cell's structure and shape c. preventing the phospholipid tails from binding together d. allowing specific substances to flow into the cell

The embedded proteins allow specific substances to flow into the cell.The phospholipid bilayer forms a stable barrier between two aqueous compartment.They embedded proteins carry the selective transportation of molecules and ensure their is cell to cell recognition.
