The B Lymphocyte Response Quiz

Where do B-lymphocytes mature?

• In the spleen

• In the thymus

• In the bone marrow

• In the lymph nodes

What is the primary function of plasma cells?

• To secrete antibodies

• To destroy infected cells

• To act as antigen-presenting cells

• To produce cytokines

What is clonal selection?

• The process of B-lymphocytes recognizing and binding to a specific antigen

• The secretion of antibodies by plasma cells

• The division of B-lymphocytes into plasma and memory cells

• The maturation of B-lymphocytes in the bone marrow

What happens during clonal expansion?

• Antigens are presented to T cells

• B-lymphocytes divide repeatedly by mitosis

• Antibodies are secreted into the bloodstream

• Memory cells are activated

What type of molecule forms a receptor on B-lymphocytes?

• Carbohydrate

• Glycoprotein

• Lipid

• Nucleic acid

What is the role of memory cells?

• To present antigens to T cells

• To secrete antibodies immediately

• To remain in the blood for a long time and provide immunity

• To destroy pathogens directly

What is the primary immune response?

• The production of antibodies by memory cells

• The initial response to a newly encountered antigen

• The activation of T cells

• The rapid response to a previously encountered antigen

What happens to plasma cells after they secrete antibodies?

• They are short-lived and their numbers drop off

• They become memory cells

• They continue to divide

• They present antigens to T cells

What is the specific function of B-lymphocytes?

• To secrete cytokines

• To activate T cells

• To destroy infected cells

• To produce one type of antibody molecule

What is the significance of the glycoprotein receptor on B-lymphocytes?

• It allows B-lymphocytes to move through the bloodstream

• It helps B-lymphocytes to divide

• It enables B-lymphocytes to secrete antibodies

• It combines specifically with one type of antigen
