Answer:
The alternative complement pathway kill the invading microbial cell by enhancing the phagocytosis of microbes by host cells.
Option: (C)
Step-by-step explanation:
- The complement pathway is an immune system which destroys the microbes with protein complex and phagocytes.
- It has tree types namely 'classical, alternative and lectin pathway'.
- In alternative complement pathway complex
protein complex kills the microbes in two ways,
- It attaches to the cell wall of the bacteria and kills by lysis
- Stimulates the formation of "Membrane Attack Complex(MAC)" which causes lysis of the bacteria.
