What is a foreign chemical that stimulates the production of antibodies?
An antigen is a foreign chemical that stimulates the production of antibodies by the immune system. Antigens can be bacteria, viruses, toxins, or other substances that are recognized as foreign by the body.
How many antigens are there in the human body?
There is no definite number of antigens in the human body as the immune system can recognize a wide range of foreign substances. Antigens can come from pathogens like bacteria and viruses, as well as from our own cells in cases of autoimmune diseases. The human body constantly encounters new antigens and can generate immune responses against them.
Substance produced by the body that destroys the antigen?
Antibodies are proteins produced by the body's immune system that specifically target and destroy antigens, such as bacteria or viruses, by binding to them and marking them for destruction.
What are molecules on the outer surface of a cell that identify it as long friend or for?
Molecules on the outer surface of a cell that identify it as "self" or "foreign" are called antigens. These antigens play a crucial role in the cell's ability to distinguish between its own cells and potentially harmful foreign cells. The recognition of self-antigens helps the immune system to tolerate the body's own cells while identifying and attacking foreign invaders.
What protects the body from free antigens?
The immune system protects the body from free antigens. It does so through the production of antibodies that recognize and neutralize antigens, as well as through the activation of immune cells, such as T cells and natural killer cells, that can directly destroy cells infected with antigens. Additionally, the immune system has memory cells that can recognize and respond more quickly if the same antigen is encountered again in the future.
What is a foreign chemical that stimulates the production of antibodies?
An antigen is a foreign chemical that stimulates the production of antibodies by the immune system. Antigens can be bacteria, viruses, toxins, or other substances that are recognized as foreign by the body.
Can antigens trigger a response of the immune system?
Anti gens bind to viruses/bacteria that 'fit' them, clumping together and allowing phagocytosis. They tend to be specific to one strain hence why we cannot vaccinate against a virus that mutates frequently or has many strains.
Antibodies work by attaching to the what making them useless?
Antibodies attach to antigens, which are foreign substances such as viruses or bacteria, to make them harmless by marking them for destruction by the immune system.
Antibodies are protein molecules that attach to?
specific foreign substances in the body, such as pathogens like bacteria or viruses. They help the immune system to identify and neutralize these harmful invaders.
React with antigens and inactivates them?
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.

Antibodies are proteins produced by the body's immune system that specifically target and destroy antigens, such as bacteria or viruses, by binding to them and marking them for destruction.
What are types of anitgen's?
There are several types of antigens, including proteins, carbohydrates, lipids, and nucleic acids. Antigens can be found on the surface of pathogens like viruses and bacteria, as well as on the surface of foreign cells or substances that enter the body. They stimulate the immune system to produce antibodies and mount an immune response.
How does the body react when antibiotics kill M. leprae?
When antibiotics kill M. leprae, antigens (the proteins on the surface of the organism that initiate the body's immune system response) are released from the dying bacteria.
What substances in a vaccine stimulates the immune system?
Vaccines typically contain antigens, which are components that mimic a pathogen, such as proteins or sugars from the virus or bacteria. These antigens stimulate the immune system to recognize and respond to the actual pathogen. Additionally, many vaccines include adjuvants, which are substances that enhance the body's immune response to the antigen, helping to produce a stronger and longer-lasting immunity.
Do Vaccines contain antigens for the bacteriavirus being vaccinated against and specifically target the B and T cells?
Yes, vaccines contain antigens derived from the bacteria or virus they aim to protect against. These antigens stimulate the immune system, specifically targeting B and T cells, which are crucial for developing an adaptive immune response. B cells produce antibodies against the antigens, while T cells help in recognizing and destroying infected cells. This targeted response prepares the immune system to respond more effectively if exposed to the actual pathogen in the future.
Antigens are substances capable of mobilizing?
