What is the difference between an immunogen and an antigen?
What is the difference between an immunogen and an antigen?
- An immunogen is recognized by the immune system while an antigen induces an immune response.
- An immunogen is a carrier molecule while an antigen is a target of the immune response.
- An immunogen induces an immune response while an antigen is recognized by the immune system. (correct)
- An immunogen is of low molecular weight while an antigen is complex in structure.
What property must an antigen possess to be immunogenic?
What property must an antigen possess to be immunogenic?
- Chemical composition
- Mode of entry
- Foreignness and genetic composition (correct)
- Size and stability
Why would a human body likely reject a pig's heart transplant?
Why would a human body likely reject a pig's heart transplant?
- Due to the genetic differences between pigs and humans (correct)
- The human body cannot recognize the pig's heart
- The pig's heart lacks immunogenic properties
- Because the pig's heart is too large for a human body
