Functions of Antibodies and Antigens

These flashcards cover the various functions of antibodies in relation to antigens, including inactivation, binding, activation of the complement cascade, and triggering inflammation.

What is one way antibodies inactivate antigens?

An antibody binds to an antigen and inactivates it.

What do antibodies do to several antigens?

Antibodies bind several antigens together.

What is activated when an antigen binds to an antibody?

The complement cascade is activated.

What effects can the activation of the complement cascade produce?

It can produce inflammation, chemotaxis, and lysis.

What happens when an antibody binds to a mast cell or a basophil?

It triggers the release of inflammatory chemicals.

How do antibodies facilitate phagocytosis?

An antibody binds to an antigen and then to a macrophage, leading to phagocytosis.
