Why Is a Cell-Mediated Immune Response More Effective Against Intracellular

question 109

Multiple Choice

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 a 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 cell containing the intracellular microorganism; antibodies can't enter cells
