What r antigens and antibodies?
explain the relationship between them. with examples
Answers
Antigens are any molecules that elicit adaptive immune responses. Antigens protrude from pathogens or other intruding substances. Antibodies are proteins found in blood plasma that attach to one particular kind of antigen and help counter its effects.
Answer:
antigen is a harmful substance which enters the body which causes the body to make antibodies as a response to fight off disease. An example of an antigen is a common cold virus which causes the body to make antibodies which help prevent the person from getting sick.
antibodies is a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood. Antibodies (also called immunoglobulins) are large Y-shaped proteins that can stick to the surface of bacteria and viruses. They are found in the blood or other body fluids of vertebrates. ... Each antibody is different. They are all designed to attack only one kind of antigen (in practice, this means virus or bacteria)
Explanation:
Antigens are molecules capable of stimulating an immune response. Each antigen has distinct surface features, or epitopes, resulting in specific responses. Antibodies (immunoglobins) are Y-shaped proteins produced by B cells of the immune system in response to exposure to antigens.
foreign antigens originate from outside the body. Examples include parts of or substances produced by viruses or microorganisms (such as bacteria and protozoa), as well as substances in snake venom, certain proteins in foods, and components of serum and red blood cells from other individuals
