Understand the role of the adaptive immune response: It is a specific defense mechanism that targets pathogens using specialized cells and molecules, including antibodies.
Learn about the function of antibodies: Antibodies are proteins that bind to antigens (foreign substances) to neutralize or mark them for destruction by other immune cells.
Identify the cell type responsible for antibody production: B lymphocytes (B cells) are specialized white blood cells that produce antibodies as part of the adaptive immune response.
Differentiate B cells from other immune cells: Natural killer (NK) cells and cytotoxic T cells are involved in killing infected or abnormal cells, while macrophages are responsible for engulfing pathogens and presenting antigens to other immune cells. None of these produce antibodies.
Conclude that B cells are the correct answer: B cells are activated when they encounter their specific antigen, leading to their differentiation into plasma cells, which are the primary producers of antibodies.
