Quizplus · Accepted Answer

Peripheral proteins of the inner surface of the plasma membrane are not made on the membrane-bound ribosomes of the RER. They are synthesized on free cytoplasmic ribosomes and then transferred to the plasma membrane. Soluble lysosomal proteins, vacuolar enzymes, and proteins of the extracellular matrix are made on the membrane-bound ribosomes of the RER.
