Honors Biology Study Sheet - Chapter 4.7-4.12; 4.15 DETAILS OF THE ENDOMEMBRANE SYSTEM AND ORIGINS OF EUKARYOTIC ORGANELLES WHAT ORGANELLES ARE CONSIDERED PART OF THE ENDOMEMBRANE SYSTEM WHAT IS THE OVERALL FUNCTION OF THE ENDOMEMBRANE SYSTEM SUMMARIZE THE FUNCTIONS OF THE ENDOMEMBRANE SYSTEM Complete this diagram (see Figure 4.12) by labeling the rough ER, smooth ER, transport vesicle, Golgi, Lysosome, and plasma membrane. Then trace the path of a protein from its site of manufacture in the RER to the outside of the cell with a red arrow. Finally, trace the path of an enzyme incorporated into a lysosome in blue. How do transport vesicles help tie together the endomembrane system? Match of Function with the Organelle _____ 1. Lipids manufactured here A. Golgi _____ 2. Small structure that makes protein B. Lysosome _____ 3. Sac of digestive enzymes C. Smooth ER _____ 4. Breaks down toxins and drugs in liver D. Rough ER _____ 5. ‘Ships’ products to plasma membrane, outside, or other organelles E. Central Vacuole _____ 6. May store water, wastes in plant cell F. Transport Vesicle _____ 7. How protein and other substances get from ER to Golgi or Golgi to lysosomes G. Ribosome _____ 8. Defective in Tay-Sachs disease COMPARING CHLOROPLASTS AND MITOCHONDRIA Both mitochondria and chloroplasts are energy converters, but their functions are quite different. Compare them by filling in the chart below: Chloroplasts Mitochondria Found in the following organisms Carries out the process of…. Converts energy of…. Into chemical energy of….. Evolved by endosymbiosis from…. ENDOSYMBIOTIC ORIGIN OF MITOCHONDRIA AND CHLOROPLASTS Describe the Endosymbiosis Theory List three observations (pieces of evidence) support the idea that mitochondria and chloroplasts were once free-living bacteria.
