Which organelle processes and modifies proteins?

Explanation:
Proteins made on ribosomes in the rough endoplasmic reticulum are prepared for their final destinations by a central processing hub—the Golgi apparatus. This organelle receives the newly formed proteins, adds or trims carbohydrate groups, and other chemical tags, and then sorts and packages them into vesicles for transport to the cell membrane, secretion outside the cell, or delivery to specific organelles. The rough ER is where proteins are synthesized and begin folding, but the main processing and modification that determines their final form and destination happens in the Golgi.
