Answer

The 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.

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.


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.


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.


What forms in the blood to help fight invading antigens?

White blood cells, specifically lymphocytes, are responsible for helping to fight invading antigens in the blood. These cells produce antibodies that target and neutralize foreign substances, such as bacteria or viruses. Additionally, white blood cells can mount an immune response to destroy these antigens and prevent infection.


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.

Large proteins of the blood and body fluids produced by the immune system in response to the invasion of the body by foreign molecules?

Antibodies are large proteins produced by the immune system that specifically recognize and bind to foreign molecules called antigens. They help the immune system to identify and neutralize pathogens such as bacteria, viruses, and other harmful substances. Each antibody is unique and can target a specific antigen.


What are proteins that destroy foreign substances called?

Proteins that destroy foreign substances are called antibodies. Antibodies are produced by the immune system in response to the presence of antigens, such as bacteria and viruses, to help eliminate these foreign invaders from the body.


How do proteins contribute to the production of antibodies in the immune system?

Proteins play a crucial role in the production of antibodies in the immune system. Antibodies are a type of protein that are produced by specialized white blood cells called B cells. These antibodies are designed to recognize and bind to specific foreign substances, known as antigens, such as viruses or bacteria. The binding of antibodies to antigens helps to neutralize or eliminate these harmful invaders from the body. In this way, proteins are essential for the immune system to effectively identify and combat infections.


How is invading bacteria detroyed?

The bacteria has tiny, oddly-shaped molecules on it's surface, which are different for every type of bacteria, these are called antigens. When a special type of white blood cell, called a lymphocyte, realises an invading bacteria is in the bloodstream, it starts to make tiny connectors called antibodies. These antibodies fit the antigens on the bacteria's surface, and join many bacteria together. Once lots of bacteria have been joined together, another type of white blood cell, called a phagocyte, engulfs them, and it will usually take a few days for all the bacteria to be destroyed.


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.


What is the difference between vaccine and antibodies?

Salman Khaliq Bajwa from PAF-KIET damigo88@live.com The difference between antibodies and vaccines are; 1. Antibodies are micro organisms in our body for our defense. Vaccines are diluted living or dead antigens. 2. Antibodies are natural. Vaccines are artificial, 3. Antibodies kill the bacteria, viruses and toxic substances in our body. Vaccines does not kill but it actually activates the antibodies in our body.
