Which organelle modifies and packages proteins and lipids for intracellular or extracellular use?

The Golgi apparatus is the organelle that modifies and packages proteins and lipids for use inside the cell or secretion outside it. Cargo arrives from the rough endoplasmic reticulum in vesicles and enters the Golgi stacks, where enzymes in successive cisternae add or remove carbohydrate chains, sulfations, phosphorylations, and other modifications. After processing, the Golgi sorts and packages the cargo into vesicles that head to their destinations—secretory vesicles for extrusion, vesicles to the plasma membrane, or lysosomes—depending on specific signaling tags. This central processing and routing sets it apart from other organelles: lysosomes degrade material, peroxisomes handle oxidation and detoxification, and mitochondria generate energy, while the Golgi handles the crucial steps of final maturation and delivery of proteins and lipids.
