By definition, antibodies act against particles, proteins, microbes, and viruses. Each antibody has to be a "match" or a "fit" to work against what it is working on. So if you have had chicken pox, you made antibodies to act against it and inactivate it. If you are exposed again, you will not get it. If you get a blood transfusion it must match or your antibodies will inactive it and will cause a reaction that will hurt you. Think of all the things you have come across: different pollen from different plants, different colds, different flu (you have to get a new shot every year as it is different), different vaccines. It just goes on and on.
B cells produce antibodies when an infectious bacterium enters the body. Antibodies are proteins that can recognize and bind to specific molecules on the surface of the bacterium, marking it for destruction by other components of the immune system.
Antibodies are produced by B cells, which are a type of white blood cell. When germs enter the body, B cells are activated to produce specific antibodies that can help target and neutralize the invading germs.
The best answer would be Antibodies; however, these do not chemically "attack" viruses or bacteria. More accurately, antibodies recognize various germs and allow the various cell types of your immune system to attack and destroy these germs directly. For more info on how this works see: http://en.wikipedia.org/wiki/Adaptive_immune_system
A vaccine is a medicine that produces immunity by generating antibodies. Vaccines contain weakened or killed germs that stimulate the immune system to produce antibodies against specific diseases, providing protection when exposed to the actual pathogen.
No, antibodies are not made of enzymes. Antibodies are Y-shaped proteins produced by the immune system and play a key role in identifying and neutralizing pathogens. Enzymes are a different type of protein that catalyze biochemical reactions in the body.
No, antibodies are produced by your body to fight infection.

antibodies
Yes, by certain white cells in the blood. Some of these cells produce free floating antibodies while others present their antibodies on their surface receptors. These different systems fight infection by different kinds of organisms.
Your body can produce antibodies in response to infections by bacteria, viruses, or other pathogens. It can also produce antibodies in response to allergens or foreign substances introduced into the body, such as through vaccinations or blood transfusions. Autoimmune disorders can also trigger the production of antibodies that mistakenly target healthy cells or tissues.
B lymphocytes are the cells that secrete the antibodies in response to infection in body.
B lymphocytes are the white blood cells that produce antibodies and are essential for the adaptive immune response. These cells recognize specific antigens, produce antibodies to neutralize pathogens, and help to activate other immune cells.
Fresh fruit is a very good way to help your body produce antibodies. There is a juice called "naked" that is very good for this. Herbal teas are also very helpful.
