GOLGI APPARATUS AND VESICLES

• WHAT IS THE GOLGI APPARATUS?

  folded membranes making cisternae
• WHAT ARE GOLGI VESICLES?


  secretory vesicles that pinch off from cisternae
• FUNCTIONS OF THE GOLGI APPARATUS AND VESICLES?

  • add carbohydrates to proteins to form glycoproteins
  • produce secretory enzymes
  • secrete carbohydrates
  • transport, modify and store lipids
  • form lysosomes
  • 'label' molecules with destination
  • products transported to cell surface in Golgi vesicles where they fuse with membrane contents inside are released
