GOLGI APPARATUS

• What is one function of the Golgi apparatus?

  Renews or modifies plasma membrane
• What is another function of the Golgi apparatus?

  Modifies or packages secretions for release
• What does the Golgi apparatus package for use in the cytosol?

  Special enzymes within vesicles
• How many flattened discs typically make up the Golgi apparatus?

  5–6 flattened discs
• Can there be more than one Golgi apparatus in a cell?

  Yes, there may be more than one
• Where is the Golgi apparatus typically situated?

  Near the nucleus
• What is the first step in the function of the Golgi apparatus?

  Products from RER arrive in transport vesicles
• What happens when transport vesicles fuse with the Golgi apparatus?

  They empty contents into cisternae
• What do enzymes do in the Golgi apparatus?

  Modify products received from transport vesicles
• What is the role of new vesicles in the Golgi apparatus?

  Move material between cisternae
• What occurs at the maturing face of the Golgi apparatus?

  The product arrives at the maturing face
• What are the types of products produced by the Golgi apparatus?

  • Membrane renewal vesicles
  • Secretory vesicles
  • Enzymes for cytosol
• What do membrane renewal vesicles do?

  Add to the plasma membrane
• What do secretory vesicles contain?

  Products to be discharged from the cell
• What happens to secretory vesicles when they reach the plasma membrane?

  They fuse and release contents outside
• What are enzymes for cytosol contained within?

  Lysosomes
• What is the function of lysosomes?

  Isolate damaging chemical reactions
