Which is a function of the Golgi apparatus?cell respirationprotein modificationdigestion of organic matter inside the celldrug detoxification

The Golgi apparatus is a crucial organelle in eukaryotic cells, primarily involved in the processing and modification of proteins and lipids. Here’s a breakdown of the functions listed in your question:

1. Cell Respiration: This process primarily takes place in the mitochondria. Thus, it is not a function of the Golgi apparatus.

2. Protein Modification: This is indeed a primary function of the Golgi apparatus. It modifies proteins that have been synthesized in the endoplasmic reticulum, adding carbohydrates and other groups to form functional proteins.

3. Digestion of Organic Matter Inside the Cell: This is primarily the function of lysosomes, not the Golgi apparatus.

4. Drug Detoxification: This function is primarily associated with the smooth endoplasmic reticulum, especially in liver cells.

Given this analysis, the correct answer is protein modification. The Golgi apparatus plays an essential role in modifying proteins before they are transported to their final destinations, either within or outside the cell.
