Proteins are synthesized in which organelle
WebbProteins are fed into the ER during translation if they have an amino sequence called a signal peptide. In 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 … Webb3 feb. 2009 · The chloroplasts of plants and green algae import a few thousand proteins to function in photosynthesis and other processes ().These proteins are believed to be synthesized at random cytoplasmic locations and to undergo posttranslational import, because isolated chloroplasts can import proteins synthesized in vitro, and EM studies …

As the protein grows, if it contains a signal sequence at its amino-terminal end, it will become bound to a signal recognition particle, which carries the ribosome to the RER membrane.
