Killer T cells must get permission from T helper cells before killing a body cell.1 True False 2. The Y-shaped antibodies that B cells make will stick to any virus.1 True False 3. Which of these cells has a perforin gun?1 NK T helper macrophage B cell dendritic cell 4. Which of these cells will eat anything that is covered in Y-shaped antibodies?1 B cell macrophage NK cell T cell 5. Which organelle digests things?1 lysosome mitochondria Golgi body ER 6. This lesson showed all the cell types in the immune system.1 True False 7. Interferon causes many anti-viral proteins to be made, and we know exactly what each one does.1 True False 8. How does RIG-1 work?1 Its shape straightens out when it is trigger. It goes into the nucleus when triggered. It kills viruses when triggered. It bends in half when triggered. 9. Which of these is NOT a sensor molecule?1 MDA-5 RIG-1 MHC-1 TLR-3 10. Why do the phagocytes (roaming eaters) have MHC-2 clips on their surface?1 For sensing viral dsRNA. For communication with other phagocytes. For showing bits of protein to T helper cells. Only for identification as "self." 11. What are granzymes?1 Granular proteins that self-assemble to make a hole. Chemical toxins that tell the cell to shred its DNA. Enzymes that digest all the proteins in the host cell. 12. Some of your cells were built with atoms and molecules that used to be part of viruses.1 True False 13. All the viral sensors are designed to stimulate production of interferon (IFN).1 True False 14. Skin is a good barrier against viruses because the outer layer is made of dead cells.1 True False 15. Which cell can feel the absence of MHC-1 flags?1 B cell NK killer T cell macrophage VIRUSES lesson 8: Viruses Inside Cells VIRUSES lesson 10: Vaccines and anti-virals Back to: VIRUSES lesson 9: The Body Fights Back
