Answer #1

Antibody is a specialized substance and it help to kill foreign invader like bacteria. Antibodies also play a major role in antibody mediated immunity during the infection.

The harmful bacteria is also killed by phogocytes process.immune system has a specialized immune proteins ( Acute phase proteins ) it is called the complement and during the infection antibodies bind to the surface of bacteria in opsonization process with the help of complement system.

Complement like C3 b it play major role in bacterial infection and it is proteins for opsonization.

Q1. An experiment studied the role of the complement system for clearance of bacteria from the blood of mice. Two types of mice were used in the study: C1q-knockout mice and wild type mice. The mice were infected with either antibody-coated or un-coated bacteria (in a fully factorial design, i.e, both mouse genotypes were exposed to both types of bacteria), and the clearance rate was measured during two hours after bacterial administration. Explain the protecting mechanisms (not only those involving...
