Smooth ER - lacks ribosomes - continuous with Rough ER https://www.youtube.com/watch?v=zxL3VcvfAVo&list=PLPiw8bMNFj13MJBsqPPS96Fyy9aXpq4Iq&index=7  Lysosome Activity Lysosomes break down bacteria!! Macrophages are white blood cells that contain many lysosomes as they are responsible for destroying bacteria, viruses, and other foreign material that invades our body! Cool video of white blood cell with lots of lysosomes attacking a giant bacterium!! https://www.youtube.com/watch?v=iZqBbAJJFzM&t=10s Mitochondrion (1) Mitochondria (many) https://www.youtube.com/watch?v=1xwaG-GBHIU&list=PLPiw8bMNFj13MJBsqPPS96Fyy9aXpq4Iq&index=9  Microtubules and Microfilaments Motor proteins interact with components of the cytoskeleton for molecular motion = Moving organelles and vesicles!! Motor proteins move vesicles and organelles by “walking” on the microtubules and microfilaments – ATP is needed!! So Cool!!! See video in Modules on Canvas: CH 6 Cytoskeleton Review Page https://www.youtube.com/watch?v=YAva4g3Pk6k&list Microtubule =PLPiw8bMNFj13MJBsqPPS96Fyy9aXpq4Iq&index=10 Motor Proteins “walk” on Microtubules and Microfilaments Motor Proteins “walk” on Microtubules and carry vesicles!!
