Which organelle is primarily responsible for packaging and distributing proteins?

The Golgi Apparatus is the organelle primarily responsible for packaging and distributing proteins. Once proteins are synthesized in the ribosomes and subsequently processed in the endoplasmic reticulum, they are transported to the Golgi Apparatus. Here, they undergo further modifications, such as glycosylation, where sugar molecules are added, and are then packaged into vesicles for transport to their next destination, which could be within the cell or secreted outside of it. This organelle acts as a sorting center, ensuring that proteins are sent to the correct location, making it essential for cellular function and communication. The role of the Golgi Apparatus is crucial in the overall process of secretion and distribution of proteins within and outside of the cell.
