<prompt> The protein synthesis is sorted out at byRibosomesMitochondriaGolgi - apparatusEndoplasmic reticulum  <response>: Golgi - Apparatus 7 RS 7thGolgi - complex or Golgi - apparatus or Dietysomes - Recent evidence suggests strongly that the complex serve as unique sorting device that recieve newly synthesized proteins The post translational modifications takes place in the golgi lumen median part where the carbohydrate and lipid precursors are added to proteins to form glycoproteins and lipo proteins respectively Ribosomes - are the centre of factories of protein synthesis Rough Endoplasmic reticulum RER synthesizes membrane lipids and secretory proteins
