A nurse teaches a patient about an antibody that binds to a toxin and prevents the toxin from attaching to body cells. Which antibody action is being described?
Correct answer: A. Neutralisation
- A. Neutralisation
- B. Phagocytosis
- C. Haemopoiesis
- D. Chemotaxis
Explanation
Neutralisation occurs when an antibody blocks a toxin or microorganism from attaching to or entering host cells. Phagocytosis is performed by cells, haemopoiesis forms blood cells, and chemotaxis attracts immune cells to a site.
