Protein A is a transmembrane protein in the plasma membrane. Its N-terminus is on the cytoplasm side and its C-terminus is on the extracellular side. During its transport through the endomembrane system, what should its orientation be in various compartments that it travels through? Determine whether the N or C-terminus of protein A should be in the lumens of ER, Golgi, and the transport vesicles.
