Describe how the nucleus, endoplasmic reticulum, ribosomes, Golgi apparatus, and vesicles work to produce protein?

The endoplasmic reticulum takes the proteins that are made by the ribosomes and folds them into sacs that are called cisternae. It then transports these folded proteins to the Golgi apparatus ... They are then released from the Golgi apparatus in what are called secretory vesicles into the cytoplasm.
