1. _____ Circle True or False. T lymphocytes require the presence of antigen presenting cells to function. 2. _____ Circle True or False. The complement system always involves the classical pathway of complement activation. 3. _____ Circle True or False. An antigen is a substance which causes the body to produce sensitized T lymphocytes. 4. _____ Circle True or False. IgM accounts for 80 percent of all antibodies in the serum. 5. _____ Circle True or False. Antigen to antibody binding can result in opsonization.
