The main organelle involved in modification and outing of newly synthesized proteins to their destinations is:
Correct answer: D. Endoplasmic reticulum.
- A. Chloroplast
- B. Mitochondria
- C. Lysosome
- D. Endoplasmic reticulum.
Explanation
The proteins formed on ribosomes pass into the ER lumen where they are modified. Then the modified proteins move on into the transitional area, where the ER buds off membranous sacs (the transport vesicles) that carry the proteins to the Golgi apparatus.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
