Which of the following is a function of the Golgi apparatus?
Photosynthesis
Protein synthesis
ATP production
Packaging and secretion of materials
Packaging and secretion of materials
The Golgi apparatus functions as the cell's 'post office' or shipping department. It is responsible for modifying, sorting, and packaging proteins and lipids synthesized in the Endoplasmic Reticulum into vesicles for secretion or delivery to other organelles.
The Golgi apparatus functions as the cell's 'post office' or shipping department. It is responsible for modifying, sorting, and packaging proteins and lipids synthesized in the Endoplasmic Reticulum into vesicles for secretion or delivery to other organelles.
Think of the Golgi apparatus as an Amazon fulfillment center: it receives products, packs them into boxes (vesicles), labels them for their destination, and ships them out.
G-P-S: Golgi Packages Secretions.
C6тАЛH12тАЛO6тАЛ тАФ Glucose molecule processed by cellular metabolism
ATPтЖТADP+PiтАЛ+Energy тАФ Cellular energy currency
Proteins synthesized in the rough endoplasmic reticulum reach the cis-face of the Golgi stack. As they transit through the cisternae, they undergo post-translational modifications like glycosylation or phosphorylation. Finally, these products are packaged into secretory vesicles at the trans-face and exported to their destination via exocytosis or to lysosomes.
It consists of flattened membrane-bound sacs called cisternae.
It is highly developed in cells involved in secretion, such as endocrine and exocrine cells.
It is the site of complex polysaccharide synthesis in plant cells.
Ensures proteins reach their correct cellular destination.
Prevents internal cell damage by segregating active enzymes.
Secretion of digestive enzymes by pancreatic cells.
Formation of lysosomes containing hydrolytic enzymes.
Discovered by Camillo Golgi in 1898.
Option A (Photosynthesis) occurs in chloroplasts.
Option B (Protein synthesis) occurs in ribosomes.
Option C (ATP production) occurs in mitochondria.
D is correct тАФ The Golgi apparatus is the primary organelle responsible for processing, packaging, and transporting proteins and lipids.
Always remember the 'Division of Labor' in eukaryotic cells: Mitochondria (Powerhouse), Ribosomes (Protein Factory), and Golgi (Shipping/Packaging).
