Answer:
c. Golgi bodies
Step-by-step explanation:
The Golgi apparatus, often referred to as the Golgi bodies, plays a crucial role in modifying and packaging cellular secretions for export from the cell. It is a cellular organelle responsible for processing, modifying, and sorting proteins and lipids that are synthesized in other parts of the cell, such as the endoplasmic reticulum (ER).
Here's how the Golgi apparatus works:
Modification: Proteins and lipids synthesized in the ER are initially in an immature, non-functional form. The Golgi apparatus modifies these molecules by adding specific chemical groups, such as carbohydrates (glycosylation), to them. This modification is essential for their proper function.
Sorting: The Golgi apparatus also sorts these modified molecules into vesicles, which are small membrane-bound sacs. These vesicles can contain various substances, including enzymes, hormones, or other proteins that need to be exported or sent to other parts of the cell.
Packaging for Export: Once sorted, the Golgi apparatus packages these vesicles for export. They can merge with the cell's plasma membrane and release their contents outside the cell through a process called exocytosis. This allows cellular secretions to be transported outside the cell to perform their functions.
In summary, the Golgi apparatus is responsible for modifying, sorting, and packaging cellular secretions for export, making it a crucial organelle in the cell's secretory pathway. This process ensures that proteins and other molecules are correctly processed and delivered to their intended destinations within or outside the cell.
