Question

multiple choice question
what is the function of transport proteins in the phospholipid bilayer?
o serve as self - identification tags
o bind to a substance on one side and trigger a reaction on the other side
o catalyze reactions that occur on the cell surface
o allow molecules to pass through the cell membrane

Explanation:

Transport proteins in the phospholipid bilayer facilitate the movement of molecules across the cell - membrane. They create channels or carriers for substances that cannot freely diffuse through the lipid - rich membrane. They do not serve as self - identification tags (that's the role of glycolipids and glycoproteins), do not mainly bind to trigger reactions on the other side in the way described, and do not catalyze cell - surface reactions (enzymes do that).

Answer:

allow molecules to pass through the cell membrane
