golgi apparatus

• What is the structure shown in the image called?

  Golgi apparatus

  
• What are the primary functions of the Golgi apparatus?

  • Modifies and sorts proteins
  • Adds carbohydrate tags
  • Packages proteins into vesicles for transport
  • Transports lipids

  
• What type of vesicles enter the Golgi apparatus?

  Incoming transport vesicles

  
• What are the two main faces of the Golgi apparatus?

  Cis face and trans face

  
• What is the lumen of the Golgi apparatus?

  The inner space of the Golgi cisternae

  
• What are the flattened, membrane-bound sacs that make up the Golgi apparatus called?

  Cisternae

  
• How do proteins move through the Golgi apparatus?

  • Enter through the cis face in transport vesicles
  • Move through the cisternae
  • Undergo modifications along the way
  • Exit through the trans face in secretory vesicles

  
• What types of tags are added to proteins in the Golgi apparatus?

  Carbohydrate tags

  
• What do secretory vesicles contain?

  Proteins and other substances for secretion

  
• What is the significance of the Golgi apparatus in protein transport?

  It modifies, sorts, and packages proteins into secretory vesicles for transport to their target locations

  
• Describe the overall function of the Golgi apparatus in the secretory pathway.

  1. Receives proteins from the ER
  2. Processes and modifies proteins
  3. Sorts proteins based on their destination
  4. Packages proteins into transport vesicles
  5. Transports proteins to their final destinations

  
• What is the Golgi apparatus made of?

  Flattened membrane sacs (cisternae)
• What is the function of the cis face of the Golgi apparatus?

  Receives proteins from the rough ER
• What happens to proteins in the Golgi apparatus?

  They are modified and packaged for secretion
