The organelle that acts like a post office by packaging and distributing proteins is the Golgi apparatus. Here's how it functions:
1. Proteins are produced in the endoplasmic reticulum (ER) of the cell.
2. The proteins are then transported to the Golgi apparatus in vesicles (small sacs) for further processing.
3. Within the Golgi apparatus, these proteins undergo modifications like folding, glycosylation (adding sugar molecules), and sorting.
4. The Golgi apparatus then packages these modified proteins into vesicles and sends them to their final destination within or outside the cell.
In summary, the Golgi apparatus plays a crucial role in modifying, sorting, and packaging proteins before they are sent to their intended locations within the cell or outside of it.
