Final answer:
The statement is true; activated T cells become killer T cells that destroy infected cells or helper T cells that regulate immune responses including antibody production by B cells.
Step-by-step explanation:
The statement is true.
Activated T cells differentiate into either killer T cells (also known as cytotoxic T cells, or Tc cells) or helper T cells (Th cells). Killer T cells have the role of destroying infected target cells or cells that are cancerous. On the other hand, helper T cells do not directly kill infected cells; instead, they manage and regulate the immune response. This regulation involves the secretion of cytokines that influence the activity of other immune cells, such as B cells and macrophages, as well as further stimulating Tc cells.
Activated B cells transform into plasma cells that produce antibodies. These antibodies are specific to antigens found on pathogens or infected cells, leading to various immune reactions such as phagocytosis, triggering of the complement system, or agglutination, which result in the destruction of these cells.
True. Activated B cells, known as plasma cells, secrete antibodies that bind to specific antigens on pathogens or infected cells. This binding forms antibody-antigen complexes that can lead to the destruction of the cells. Additionally, activated T cells, such as killer T cells, are responsible for destroying cells that are infected with pathogens or cancerous. They do this by identifying and killing infected target cells before the pathogen can replicate and escape.
