  1. Cell Endomembrane System Presented by Hongbo Reiko Chengxu Caitlin Shu Hui Wei Ying

  2. Properties of endomembrane system • present only in eukaryotic cells • transport system for moving molecules through interior of the cell • made of lipid bi-layer with proteins attached to either side or transversing them • divides cell into organelles

  3. Parts of the endomembrane system • Plasma Membrane • Endoplasmic Reticulum • Golgi Apparatus • Lysosome • Vacuoles • Vesicles • Nuclear Envelope

  4. Plasma Membrane • separates cell from outside environment and regulates transport of molecules and signals into and out of the cell and communications with other cells • Semi-permeable • Attachment point for the intracellular cytoskeleton

  5. Endoplasmic Reticulum: Bio synthetic factory • synthesis and transport organelle which is an extension of the nuclear envelope • interconnected network of tubules, vesicles, and cisternae • responsible for protein translation, folding and transportation of proteins

  6. Golgi Apparatus: Shipping and Receiving Center • packaging and delivery system for molecules • processes and packages molecules synthesized by cell • molecules primarily proteins and lipids

  7. Lysosome:Digestive Compartments • breaking down of macromolecules • contains acid hydrolases • digest worn out organelles, food particles and viruses/bacteria

  8. Vacuoles: Diverse Maintenance Compartments • membrane bound compartment • secretory, excretory and storage function

  9. Vesicles • store, transport or digest cellular products and waste • basic tool for organizing metabolism, transport, enzyme storage and are chemical reaction chambers

  10. Nuclear envelope • nucleus is not part of the endomembrane system • encloses genetic material • nuclear pores present on surface to regulate transport

  11. Relationships among organelles of endomembrane system • Nuclear envelope • Rough ER • Smooth ER • Vesicles • Golgi Apparatus • Lysosome • Vacuoles • Plasma Membrane
