Multiple Choice

Antibodies are a part of which type of immunity and why?

Adaptive immunity; Antibodies recognize specific antigens/pathogens.

Innate immunity; Antibodies are able to recognize any type of antigen/pathogen.

Evolutionary immunity; Antibodies can easily change to recognize any new antigen/pathogen.

Verified step by step guidance

Understand the two main types of immunity: innate and adaptive. Innate immunity is the body's first line of defense and is non-specific, meaning it does not target specific pathogens. Adaptive immunity, on the other hand, is specific and targets particular pathogens.

Recognize that antibodies are proteins produced by B cells, a type of white blood cell, as part of the adaptive immune response. They are designed to recognize and bind to specific antigens, which are unique molecules found on the surface of pathogens.

Consider the role of antibodies in adaptive immunity. They help to neutralize pathogens by binding to antigens, marking them for destruction by other immune cells, or preventing them from entering cells.

Evaluate the statement that antibodies are part of innate immunity. This is incorrect because innate immunity does not involve the production of antibodies or the recognition of specific antigens.

Reflect on the concept of evolutionary immunity. While the immune system can adapt over time through processes like somatic hypermutation and clonal selection, antibodies themselves do not change easily to recognize new antigens. This adaptability is a feature of the adaptive immune system, not a separate type of immunity.
