- antibodies and defences
- defences
- primary defences include skin, mucus, scabs, hair
- secondary defence is your immune system
- variable region
- they form thr antigen bonding sites
- the variable region is complementary to a specific antigen and so the variable region VARIES with each antibody
- Hinge region
- allows felixibility when the antibody binds to the antigen
- constant region
- allows binding to receptors on neautrophils etc
- disulfide bridge
- holds the polypeptide chains together
- was in which antibodies work
- agglutinating
- 2 binding sites allow 2 antigens to bind at the same time
- they clump togther and so when phagocytes engluf, many can be eungulfed at once
- neutralisation
- natibodies bimd to the toxins themselves
- this means the toxins cannot affect and human cells now as theres no binding site
- toxin-antibody complexes are formed
- agglutinating
- defences
