IMMUNOLOGY

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: -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.

Detailed explanation-3: -Antibodies may be produced when the immune system mistakenly considers healthy tissue a harmful substance. This is called an autoimmune disorder. Each type of antibody is unique and defends the body against one specific type of antigen.

Detailed explanation-4: -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-5: -The antibody binds to specific antigens. This signals the other cells of the immune system to get rid of the invading microbes. The strength of binding between the antibody and an antigen at a single binding site is known as the antibody’s affinity for the antigen.

Detailed explanation-6: -A type of white blood cell called a lymphocyte recognises the antigen as being foreign and produces antibodies that are specific to that antigen. Each antibody has a unique binding site shape which locks onto the specific shape of the antigen.

Detailed explanation-7: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.
