What the golgi body looks like.
Golgi Apparatus
Golgi Apparatus






Function:
  • Proteins are bundled into tiny vesicles and delivered to the Golgi apparatus
  • The Golgi apparatus modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell
  • The Golgi apparatus puts the final touches on proteins before they are moved to their final destination
  • Important role in the synthesis of proteoglycans

Structure:
  • Made up of membrane-bound structures called cisternae
  • Cisternae have a flat, membrane enclosed disc that contains special golgi enzymes that modify or help to modify proteins that travel through them
  • Individual stack is called a dictyosome

  • Each cisternae carries structural proteins that are important for their maintenance
Normally 4-8 per stack, as many as 60
  • Mammalian cells usually contain 40-100 stacks
  • Cisterae stacks are divided into four functional regions
    • Cis-Golgi network
    • Medial Golgi
    • Endo-Golgi
    • Trans-Golgi network
    • Each region contains different enzymes that selectively modify the contents depending on which region they are in
