Biology 4.1.1 Antibodies
Fichas del conjunto (8)
- 1What are antibodies made of?Glycoproteins (amino acids and sugars)
- 2Where is the variable reigon? What is its function?Found on the ends of the "Y"
It is the antigen binding site which is complementary to the specific antigen
- 3What bond is found between polypeptides?Disulphide
- 4What is the constant reigon? What is its function?"Constant portion" on diagram
Phagocytes have specific receptors for this reigon which is same for all antibodies - 5What is the hinge reigon? What is its function?Allows flexibility in binding antigens
- 6What is agglutination?Large antibodies binding pathogens together making bacteria easier to englufand prevent viruses entrering host cells
- 7What are antitoxins?Antibodies that act as anti-toxins by binding to toxins produced by pathogens, making them harmless
- 8What is the difference between a persons first and second immune response?The first time, clonal selection and expansion take longer and less antibodies are produced, making us ill.
The second time, memory cells allow us to produce antibodies quickly and in high numbers and the pathogen is destroyed before the person experiences any symptoms
