Question: What is the role of the complement system in the antigen-antibody reaction?

Options:

Correct Answer: To enhance phagocytosis and lyse pathogens

Solution:

The complement system enhances phagocytosis and can directly lyse pathogens when activated by antibody-antigen complexes.

What is the role of the complement system in the antigen-antibody reaction?

What is the role of the complement system in the antigen-antibody reaction?

Step 1: Understand that the complement system is a part of the immune system that helps fight infections.
Step 2: Know that antibodies are proteins produced by the immune system to identify and neutralize pathogens like bacteria and viruses.
Step 3: Learn that when antibodies bind to pathogens, they form what is called an antigen-antibody complex.
Step 4: Recognize that this complex can activate the complement system.
Step 5: Understand that once activated, the complement system can enhance phagocytosis, which is the process where immune cells engulf and destroy pathogens.
Step 6: Realize that the complement system can also directly lyse (break apart) pathogens, leading to their destruction.
