What is protective antigen?
The protective antigen is the antigen an antibody binds to killing the pathogen. It more or less is the "kill spot" for the pathogen. Also known as protective epitope.
Small piece of a pathogen that generates an immune response?
antigen
Substance that the body regards as foreign?
If it can be harmful, it can be referred to as pathogen.
What molecule is connected to the surface of pathogens?
An antigen is a molecule that is located on viruses, bacteria, cancer cells, and other pathogens. An antigen is very specific to each pathogen. A flu antigen is different from a pneumonia antigen, and an HIV antigen is different from a measles antigen. I like to think of an antigen as a lock, understanding that all locks are different and very specific. The key that fits these antigen locks is called an antibody. Antibodiesare found on certain types of white blood cells that our body produces. Antibody-producing white blood cells are called lymphocytes. Lymphocytes travel around our body and attach antibodies to pathogen antigens. Once an antigen has an antibody attached to it, phagocytes attack the pathogen, engulf it, and kill it. Sometimes the antibody disables the pathogen so that it cannot reproduce or release toxins.SourceBYU Course BIOL 049 Lesson 3
Does the first exposure to a pathogen result in a much faster immune response than the second exposure to the same pathogen?
After your first exposure to a pathogen, you have memory T-cells that will remember the antigen of the pathogen so in the future if you would come in contact with the same pathogen your body would recognize it right away and be able to kill it much faster.
What is the difference between antigens and pathogen's?
An antigen is a body's system for creating antibodies to fight infection. A pathogen is an infectious agent (or germ).
What is the relationship between antigen and antibody?
Basically to explain this, an antigen is any type of pathogen that causes disease, while an antibody is something that combats against the antigen.
Is a virus an antigen?
no its a pathogen
What is protective antigen?
The protective antigen is the antigen an antibody binds to killing the pathogen. It more or less is the "kill spot" for the pathogen. Also known as protective epitope.
What is the function of an antigen in an antigen-antibody response?
To help immune cells identify and destroy a pathogen
How does the body recognize when a foreign pathogen has entered?
Antigen
What chemical can destroys a pathogen by locking onto it antigen?
An Antibody.
What chemical destroys a pathogen by locking onto its antigen?
An Antibody.
Small piece of a pathogen that generates an immune response?
antigen
What is the foreign material called that stimulates the production of an antibody?
do you mean antigens? An antigen is any (foreign) substance that stimulates an immune reaction.
What is the difference between soluble and particulate antigen?
A soluble antigen is a viral antigen that remains after the virus has been removed. A particulate antigen is produced by particles such as dust and germs.
Which of the following is NOT true about antibodies a. an antibody has more than one antigen binding site b. a pathogen can have different epitopes c. a pathogen makes more than one antigen?
C is false.A pathogen can have multiple epitopes and antigens. A single antigen is simply one molecule, and the cell surface is littered with millions of antigens.
