Where Do Newly Synthesized Proteins Go? 1) They are released outside the cell 2) They are inserted into the cell membrane 3) They remain in the cytoplasm as soluble proteins 4) They are used to maintain organelle function, either as part of an organelle’s structure (eg. in its membrane), or inside the organelle.
