Answer:
O ribosomes bound to rough endoplasmic reticulum, vesicles, Golgi apparatus, vesicles
Explanation:
→Ribosomes bounded to R.ER are responsible for the mediation of the process of translation and elongation of the amino acids chains during protein synthesis for gebe expression. These R.ER bounded ribosomes are concerned for the synthesis of proteins for excretion out of the cells.
→As the protein chains were eleongated on the ribosomes units they are pushed into the lumen of R.ER into the intracistern space.Therefore R.ER is concerned with synthesis and packaging of protein synthesised by the attached ribosomes,
→These proteins are transported in vesicles,( which move through the cytoskeleton of the Cystosol) which budded off from the R.ER membranes.These vessicles transport the synthesized proteins to the Golgi complex.
→The Golgi apparatus receive the protein from the (R.ER), process it, and sorted it out into its vesicles(Golgi vesicles) for onward secretion out of the cells through excytosis from the plasma membranes. Example of this sorting and processing by the Golgi apparatus is the formation of Glycoprotein by addition of sugars molecules to proteins .
