True or false. For the next few questions mark true or false, if false, change one word or phrase to make the statement true. a. Antibody heavy-chain are highly variable for antigen recognition. b. An autoimmune disorder occurs when T-cells mistake self-proteins for non-self. c. The major histocompatibility complex is used by cells to mark apoptosis in progress. d. Cytokines signal the immune system to make antibodies, and are produced by Cd8 (T-killer) cells. e. Antibodies bind to antigens on viruses improving viral function within the body. f. Antigens are typically long hydrophobic hydrocarbon chains added to proteins. Compare and contrast systemic versus cellular immune response. Be sure to mention how each function in the immune system. (histamine, edema, macrophages, B-lymphocytes, and T-lymphocytes) Briefly discuss or sketch how B-cells initiate antibodies. (IgM vs IgG). A cell in your body has been infected with a virus, and has begun expressing viral proteins. List the steps, and molecules involved in antibody production. Discuss/draw the pathway taken by the protein ATPsynthase and then collagen.
