Lesson Flashcards: Structure and Function of Antibodies Biology


The clumping together of pathogens that makes it easier for phagocytes to engulf and digest them

Complementary binding

The description of how two molecules can bind together due to their shapes and the intermolecular forces they are able to form between them


The ability of antibodies to block the binding site (or binding sites) on viruses that they use to enter their target cell, making the pathogen no longer infectious


The process in which soluble antibodies and antigens precipitate out of a solution through complementary binding to form an insoluble antigen–antibody complex


Specific antibodies that bind to toxins produced by pathogens so that the toxins no longer have a harmful effect

B lymphocytes

Lymphocytes that mature in bone marrow and secrete antibodies

Antibody (immunoglobulin, Ig)

A globular protein produced by B lymphocytes that is adapted to bind with a specific antigen


Substances that can trigger an immune response
