Final answer:
The respiratory burst reaction activates the complement system, which helps eliminate pathogens by playing a role in inflammation, opsonization, and the formation of the membrane-attack complex (MAC).
Step-by-step explanation:
The respiratory burst reaction has several important effects on the immune response. One of these effects is the activation of the complement system. The complement system is a part of the immune system that helps to eliminate pathogens. It plays a role in the inflammation process, opsonization of pathogens for phagocytosis, and the formation of the membrane-attack complex (MAC) which can kill certain pathogens.
