ANATOMY

Detailed explanation-1: -Each antibody can only recognize and bind one specific type of antigen. They are a type of killer T cell. They induce a specific immune response involving the adaptive immunity. Antigens are very similar to molecules found on the outside of cells.

Detailed explanation-2: -Because one antibody only recognizes a specific antigen, antibodies that attack cancer cells, for example, do not attack normal cells. This is called the “specificity” of an antibody toward that antigen.

Detailed explanation-3: -A protein made by plasma cells (a type of white blood cell) in response to an antigen (a substance that causes the body to make a specific immune response). Each antibody can bind to only one specific antigen. The purpose of this binding is to help destroy the antigen. Some antibodies destroy antigens directly.

Detailed explanation-4: -THE TWO BINDING SITES of most antibodies can bind only one type of antigen.

Detailed explanation-5: -Antibodies are host proteins that are produced by the immune system in response to foreign molecules that enter the body. These foreign molecules are called antigens, and their molecular recognition by the immune system results in selective production of antibodies that are able to bind the specific antigen.
