12 Questions
What is the main characteristic of an immunogen?
Capable of inducing an immune response, whether humoral or cell mediated or both
What is the role of an epitope in an antigen?
Structure in the antigen recognized by the B or T cells
Which property of an antigen refers to its genetic foreignness to the host?
Foreignness and genetic composition
What type of molecule is a hapten?
Low molecular weight molecule that must bind to a carrier molecule to trigger immune responses
Why might a human body reject a transplanted pig's heart?
The pig's heart is genetically different from humans
Which characteristic of an antigen affects whether it can provoke an immune reaction?
Genetic composition
Which type of substances are generally NOT antigenic?
Pure lipids and nucleic acids
Why are proteins considered to be the most immunogenic?
Due to their larger molecular size and complex structures
What property of an antigen can affect its immunogenicity besides its chemical composition?
Antigen's stability in the body
In what way does a glycoprotein differ from a pure protein that makes it more antigenic?
Glycoproteins have a more complex structure than pure proteins
What type of molecules are considered weakly immunogenic or not immunogenic at all?
Molecules below 10,000 Dalton's
Why do some high molecular weight substances lose their immunogenicity in the body?
They break up into smaller molecules once inside the body
