Answer:
Globular proteins
Explanation:
The cell membrane has phospholipid bilayer which consists of several molecules such as proteins and cholesterol which helps in movement of compounds across the cell membrane through facilitated diffusion.
Globular protein is one these molecules which act as a transport molecule. It has a carbohydrate chain that gets embedded in the cell membrane and help in communicating from one cell to other thereby allowing transportation of large carbohydrate molecule.
