B) They transport transmembrane proteins and GPI-linked proteins from the Golgi to the plasma membrane.
C) They transport proteins from the ER to the Golgi.
D) They form a rigid complex capable of protecting protein structure and orientation as it is passed from hydrophobic to hydrophilic environments.
E) None of the above.
Answer: B) They transport transmembrane proteins and GPI-linked proteins from the Golgi to the plasma membrane.
