What is the primary function of an antibody in response to antigen exposure?
What is the primary function of an antibody in response to antigen exposure?
- To recognize and bind to a specific epitope with low specificity
- To destroy the antigen without binding to it
- To recognize and bind to a particular antigen with high specificity (correct)
- To inhibit the immune response to the antigen
What is the typical size of an epitope?
What is the typical size of an epitope?
- 15-20 amino acids
- 5-7 amino acids
- 10-12 amino acids (correct)
- 20-25 amino acids
What is the result of the interaction between an antibody and an antigen?
What is the result of the interaction between an antibody and an antigen?
- The antibody changes shape, exposing a new site for antigen binding (correct)
- The antibody and antigen bind, but the immune response is inhibited
- The antigen changes shape, making it more susceptible to destruction
- The antibody and antigen remain unchanged, but the immune response is triggered
