Which of the following is the function of Golgi Complex?

Correct answer: D. Processing of cell secretions

  • A. Intracellular digestion
  • B. Autophagy
  • C. Autolysis
  • D. Processing of cell secretions

Explanation

The Golgi apparatus processes and packages cell secretions by receiving proteins and lipids from the endoplasmic reticulum in transport vesicles, modifying them through post-translational changes such as glycosylation, sorting them based on destination signals, and then packaging them into membrane-bound vesicles. These vesicles can become secretory vesicles for export, lysosomes for intracellular digestion, or other types. Once packaged, the vesicles bud off from the Golgi and are transported to their target locations, where they fuse with membranes to deliver their contents, playing a crucial role in the secretion and distribution of cellular molecules.

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.
