A)lysozyme production.

E)lysis by natural killer cells.

Question

Quizplus · Accepted Answer

Antibody production by plasma cells is a crucial defense mechanism against extracellular pathogens, particularly during prolonged exposure. Antibodies bind to specific foreign antigens on the pathogen's surface, signaling to phagocytic cells to engulf and destroy them. This process facilitates the clearance of the pathogen and helps prevent its spread. Choices A, B, D, and E represent other immune responses, but they are not specifically highlighted as significant defenses against prolonged exposure to extracellular pathogens.
