WebIn general, proteins bound for organelles in the endomembrane system (such as the ER, Golgi apparatus, and lysosome) or for the exterior of the cell must enter the ER at this stage. Proteins that do not have a signal peptide stay in the cytosol for the rest of translation. Web3 Aug 2024 · Such pathways are accomplished by the fusion of membrane-bound vesicles or organelles with the plasma membrane.
