Why is a cell-mediated immune response more effective against intracellular microorganisms (such as viruses) than an antibody-mediated response?
A) Cell-mediated (vs. antibody-mediated) response results in activation of many more immune cells, so it is more effective at destroying antigens.
B) Intracellular microorganisms are too large for antibodies to be effective against.
C) Intracellular microorganisms are too small for antibodies to be effective against.
D) Cell-mediated response results in destruction of cells containing the intracellular microorganism; antibodies can not enter cells.
Intracellular Microorganisms
Microorganisms that live within the cells of a host, often causing disease or infection.
Cell-Mediated
Referring to immune responses that do not involve antibodies but rather the activation of phagocytes and antigen-specific cytotoxic T-lymphocytes.
Antibody-Mediated
Refers to the immune response that involves the production of antibodies by B cells to target and neutralize foreign invaders like bacteria and viruses.
- Differentiate between the actions of antibody-mediated immunity and those of cell-mediated immunity.
- Identify the function of different immune system elements in protection against pathogens inside and outside cells.

Final Answer :
D
Explanation :
Cell-mediated immunity specifically targets and destroys infected cells, effectively eliminating intracellular pathogens like viruses, which hide inside cells where antibodies cannot reach them.
