The organelle responsible for packaging proteins is the Golgi apparatus. This organelle plays a crucial role in modifying, sorting, and packaging proteins and lipids for secretion or for use within the cell.
Here’s how it works:
- Proteins are first synthesized in the rough endoplasmic reticulum (ER).
- These proteins are then transported to the Golgi apparatus in vesicles.
- Once inside the Golgi apparatus, the proteins undergo further modifications, such as the addition of carbohydrates (glycosylation).
- The Golgi apparatus then sorts these proteins and packages them into new vesicles.
- These vesicles can either be sent to other parts of the cell or to the cell membrane for secretion outside the cell.
In summary, the Golgi apparatus is essential for the proper processing and distribution of proteins within the cell.
