Which Of The Following Proteins Are Synthesized By Bound Ribosomes

Which Of The Following Proteins Are Synthesized By Bound Ribosomes – The ribosome is a complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules. Ribosomes consist of two major components: the small ribosomal subunits, which read the RNA, and the large subunits.

Which Of The Following Proteins Are Synthesized By Bound Ribosomes

Which Of The Following Proteins Are Synthesized By Bound Ribosomes – When a ribosome begins to synthesize proteins that are needed in some organelles, the ribosome making this protein can become “membrane-bound”. In eukaryotic cells this happens in a region of the endoplasmic reticulum (ER) called the “rough ER”. The newly produced polypeptide chains are inserted directly into the ER by the ribosome undertaking vectorial synthesis and are then transported to their destinations, through the secretory pathway. Bound ribosomes usually produce proteins that are used within the plasma membrane or are expelled from the cell via exocytosis.

Which Of The Following Proteins Are Synthesized By Bound Ribosomes – Proteins synthesized by Bound Ribosome: ER protein, insulin and lysosomal enzymes.
