VIRUSES lesson 9: The Body Fights Back Quizellenjmchenry2020-05-22T12:10:57-04:00 Please sign up for the course before taking this quiz. How does RIG-1 work?1 Its shape straightens out when it is trigger. It bends in half when triggered. It goes into the nucleus when triggered. It kills viruses when triggered. Why do the phagocytes (roaming eaters) have MHC-2 clips on their surface?1 For showing bits of protein to T helper cells. For sensing viral dsRNA. Only for identification as "self." For communication with other phagocytes. Interferon causes many anti-viral proteins to be made, and we know exactly what each one does.1 True False Which organelle digests things?1 Golgi body lysosome ER mitochondria The Y-shaped antibodies that B cells make will stick to any virus.1 True False This lesson showed all the cell types in the immune system.1 True False Some of your cells were built with atoms and molecules that used to be part of viruses.1 True False What are granzymes?1 Enzymes that digest all the proteins in the host cell. Granular proteins that self-assemble to make a hole. Chemical toxins that tell the cell to shred its DNA. All the viral sensors are designed to stimulate production of interferon (IFN).1 True False Which cell can feel the absence of MHC-1 flags?1 killer T cell B cell macrophage NK Killer T cells must get permission from T helper cells before killing a body cell.1 True False Which of these cells will eat anything that is covered in Y-shaped antibodies?1 B cell macrophage NK cell T cell Which of these is NOT a sensor molecule?1 MHC-1 TLR-3 MDA-5 RIG-1 Skin is a good barrier against viruses because the outer layer is made of dead cells.1 True False Which of these cells has a perforin gun?1 B cell macrophage T helper dendritic cell NK VIRUSES lesson 8: Viruses Inside Cells VIRUSES lesson 10: Vaccines and anti-virals Back to: VIRUSES lesson 9: The Body Fights Back
