Glycoproteins that react specifically with the chemical structures in the antigen that induced them are called what?
antibodies
Which of the following is not an antigen that may be found on the surface of an erythrocyte a A antigen b B antigen c O antigen d Rh antigen?
A antigen
What are antigens and how do lymphocytes recognize them?
it specifically recognise the antigenic determinants called epitopes and the similar sequence of that particular epitope will be produced by the antibody at is variable region(specifically hypervariable region) whch make an antibody to get more affinity over that particular antigen..almost antibodies are available for almost all the antigens in our body(memory cells)and they starts increasing in numbr once an antigen enters our body
What is the molecule that can be recognized by the immune system?
Antigens.
What are antigens and antibodies?
antigen-a toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.Antibodies-a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
What is antigen in German?
Abwehrstoff or Antigen
In order for a lymphocyte to respond to an antigen the antigen must?
the antigen must bind to the receptor
Why does a macrophage place antigens on its surface?
When a macrophage engulfs a foreign antigen, it phagocytizes it (or breaks it down) using enzymes. The fragments (called epitopes) of the original antigen are transported to the cell surface so that helper T-cells that specifically match the antigen can recognize it. When that happens, the helper-T cells are able to trigger a specific immune response to that exact antigen by stimulating more helper-T cells to be produced and by triggering B-cells to secrete antigen-specific antibodies that mark infected cells for destruction by killer T-cells.
What is a substance usually a protein that causes the formation of an antibody and reacts specifically with that antibody?
An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).
When silver and iodine combine what does it create?
An ionic compound, specifically a salt, named silver iodide.
What is antigene and antibody?
An antigen is a substance that can invoke an immune response. While an antibody is the immune system's response to an antigen. Antibodies, act by directly neutralizing the antigen and/or bind to the antigen and signaling marcophages to phagocytose the antigen.
What is the protein made in a response to a specific antigen called?
An antigen is a protein made in response to a specific antigen.
