Phagocytes kill bacteria through which mechanism_____________?
Correct answer: B. Oxidative and non-oxidative killing
- A. Membrane attack complex killing
- B. Oxidative and non-oxidative killing
- C. Zipper killing
- D. Chemotaxis
Explanation
Phagocytes destroy ingested bacteria through oxidative mechanisms, such as reactive oxygen species and myeloperoxidase, and non-oxidative mechanisms involving lysosomal enzymes and antimicrobial proteins. Chemotaxis only brings the cells to the site and does not kill bacteria.
