Presentation Transcript

  1. TheGOLGI APPARATUS By Alexander Severns and Evan Amendola

  2. Structure • Composed of stacks of membrane bound structures known as cisternae (flat disc like structures) • A mammalian cell’s Golgi Apparatus typically contains 40-60 stacks • 4-8 cisternae per stack usually • 2 MAIN FUNCTIONAL REGIONS/ NETWORKS • Cis-Golgi • Trans-Golgi

  3. Cis Face/Trans Face • Vesicles at the endoplasmic reticulum combine at the cis face to form a cisternae • After various chemical reactions and reconstructions have been completed in the body of the Golgi Apparatus, the vesicles exit through the Trans Face.

  4. Functions • Important to the modification and packaging of macromolecules for exocytosis or “cell secretion”. • Modifies proteins from the rough endoplasmic reticulum, as well as the transport of lipids and creation of lysosomes. • Modifies proteins by incorporating carbohydrates through use of enzymes. • Plays an important role in the synthesis of cellular and extracellular particles. • Has an assumed role in apoptosis or cell death.

  7. QUIZ TIME What best describes the structure of the Golgi Apparatus? -Spherical -Stacks of Cisternae -Polysaccharide Chains -Polypeptide Chains

  8. No! • Back To Question

  9. Yes! Good Job! • Next Question

  10. Quiz Time #2 • How many Cisternae are typically in a stack? • 25-20 • 40-60 • >9,000 • 4-8

  11. Correct! Proceed

  12. Incorrect • Try Again!
