Which cell structure is described as processing and packaging proteins?

Which cell structure is described as processing and packaging proteins?

• A. Endoplasmic reticulum
• B. Golgi apparatus
• C. Lysosome
• D. Peroxisome

Answer: (A)

Proteins are processed and packaged by the Golgi apparatus. After proteins are made and folded in the rough endoplasmic reticulum, they are transported in vesicles to the Golgi, where they receive further modifications and are sorted. The Golgi then packages these proteins into vesicles that bud off to be secreted outside the cell or delivered to specific destinations such as lysosomes or the plasma membrane. The endoplasmic reticulum handles the initial synthesis and folding, while lysosomes and peroxisomes are more involved in breakdown and metabolism rather than packaging of proteins. So the structure best described as processing and packaging proteins is the Golgi apparatus.
