Antibody-Mediated Immunity is Particularly Effective Against

Question

Antibody-mediated immunity is particularly effective against
A) extracellular pathogens.
B) intracellular pathogens.
C) both extra- and intra-cellular pathogens.
D) None of the answers are correct.

Accepted Answer

Antibodies are produced by B cells and are effective against extracellular pathogens such as bacteria, viruses in their extracellular form, and toxins. Antibodies act by binding to foreign substances and marking them for destruction by other immune cells. However, they are not very effective against intracellular pathogens that reside within host cells.
