Three organelles must work in tandem to create and package a protein, which is a macromolecule vital to all living organisms. describe how these organelles function together to create a protein

The three organelles are  a. Endoplasmic reticulum (ER) b. Golgi apparatus c. Ribosomes.

The rough endoplasmic reticulum has numerous ribosomes bound to its outer membrane hence referred to as RER. When the ribosomes translate proteins, they enter the cisternae of the RER. Here, the protein is processed, folded, and modified. This occurs as it passes from the cis to the trans face of the RER. The mature protein is then packaged by the Golgi apparatus and transported to its destination in secretory vesicles.
