Proteins made on the rough endoplasmic reticulum are modified, sorted and packaged for export by the

Correct answer: D. Golgi apparatus

  • A. lysosome
  • B. nucleolus
  • C. peroxisome
  • D. Golgi apparatus

Explanation

Vesicles carry newly made protein from the endoplasmic reticulum to the Golgi, where sugars are added, the product is sorted and it is packed into vesicles for secretion or for use inside the cell. Cells that secrete heavily, such as those of the pancreas, have a large and active Golgi. Lysosomes are one of the products of the Golgi rather than an alternative to it.

About Cytoplasmic Organelles

Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.
