AnswerThe human body makes specific antibodies to specific antigens (ex. proteins on a bacterial membrane) that it encounters. Bacteria do not all have the same antigens.* antibodies react specifically with an antigen
There are four reactions when antibodies react with antigens: agglutination, precipitation, neutralization or activation of complement. Agglutination is the clumping process that you are looking for.
This describes the role of antibodies in the immune response. Antibodies bind to antigens, such as viruses or bacteria, and either mark them for destruction by other immune cells or neutralize their effects. This process helps the immune system to recognize and eliminate harmful invaders.
The blood type notation A Rh- indicates which antigens and antibodies are present in the blood. A indicates there are A antigens. Rh+ indicates there are Rh antigens. B antibodies. If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
As Blood type O contains Anti-A-Antibodies and Anti-B-Antibodies (not Antigens) Anti-A-Serum contains Anti-A-Antibodies (which reacts with A antigen not antibody) Anti-B-Serum contains Anti-B-Antibodies (which reacts with B antigen not antibody) so antibody in antiserum will not find any antigen in blood-group O to react with so no Clumping
Antibodies are produced in response to antigens. If you get infected with one of the 200 viruses that cause colds, these viruses are antigens and your body will respond by making antibodies. The antibodies will inactivate the virus. It usually takes 7-10 for the process to be complete.
Function of antibodies is to neutralizes the antigens that enters.
true
Glycoproteins that react specifically with the chemical structures in the antigen that induced them are called antibodies. Antibodies are produced by the immune system in response to the presence of antigens, and they bind to these specific structures to neutralize or mark them for destruction by other immune cells.
Antigens
Antibodies attach to antigens preventing them from attacking cells in the body. Antitoxins attack antigens and destroy them
Antibodies primarily target extracellular antigens, which are found outside of cells. These antigens can be on the surface of pathogens or released into the extracellular environment. Intracellular antigens, located inside cells, are primarily targeted by T cells of the immune system.
