John frequently encountered bacterial infections. Tests for immune cells showed the presence of mature B and T cells in his blood. Extensive analysis showed that John was lacking a gene responsible for a protein for complement factor C5.   1. Which immune response will be inhibited because of C5 deficiency?    2. How would it affect John’s ability to fight infections? Specifically what type of infections is he likely to have difficulty fighting? Please explain in detail.    3. What would have been the implications if he was
