Which of the following describes the role of the Golgi apparatus in neurons?

• A. Post-translational protein modification.
• B. Protein synthesis.
• C. Packaging neurotransmitters into vesicles.
• D. Generation of ATP in mitochondria.

Answer: (A)

The Golgi apparatus mainly handles post-translational processing of proteins. After proteins are synthesized, they arrive at the Golgi where they undergo modifications such as glycosylation, sulfation, and phosphorylation, and then are sorted and packaged for delivery to their destinations (membrane, secretory vesicles, or lysosomes). This processing is essential for proper protein folding, targeting, and function in neurons. Generating ATP happens in mitochondria, not the Golgi, and protein synthesis occurs on ribosomes (often associated with the rough endoplasmic reticulum), not in the Golgi. Packaging proteins into vesicles is part of the broader secretory pathway, but the defining role of the Golgi is these post-translational modifications and sorting.
