Show transcribed image text Which of the following statements about immunoglobulin light chains is true? 1. Each immunoglobulin monemer has either one kappa or one lambda chain. 2. There are tow types: kappa and lambda 3. They consist of constant regions only 4. They form part of the Fc fragment Which of the following is true regarding immunoglobulins? 1. Immunoglobulins are also called antibodies. 2. They ar ethe major mediator of specific humoral immunity. 3. Immunoglobulins exist preformd on the surface of B lymphocytes. 4. All of the above A child has chicken pox and recovers. Later, she is exposed to chicken pox and does not get sick, but when she is exposed to influenza she does get sick. The is an example of 1. adaptive immunity 2. vaccination 3. nonspecific immunity 4. innate immunity All of the following are functions of monocytes/macrophages except 1. phagocytosis 2. cytokine secretion 3. lysis of host cells infected with virus 4. antigen presentation to T lymphoctes Which statement below is TRUE regrading B lymphocytes? 1. B memory cells can live for years and reactivate quickly if they encounter the same antigen. 2. B cells are taught to discriminate 'sell" antigense from "non-self" antigens in the thymus. 3. When mature B lymphocytes are released from the bone marrow, they begin secreting antibody. 4. B cell antibody response is generally very effective against viruses contained within host cells. 5. All of the above All of the following is TRUE about IgM excepty 1. is a pentamer 2. contains a J chain 3. contains secretory piece 4. first antibody class to be secreted in a primay infection 5. Most efficient activator of complement via the classic pathway
