in addition to making secretory proteins, the rough er makes membranes that grows in place from the addition of proteins and phospholipids. as polypeptides intended to be membrane proteins grow from the ribosomes, they are inserted into the er membrane itself and are kept there by their hydrophobic portions. the rough er also produces its own membrane phospholipids; enzymes built into the er membrane assemble phospholipids. the er membrane expands and can be transferred by transport vesicles to other components of the endomembrane system.
