complete each sentence explaining antibody function by selecting the proper term from each drop - down.

1. interestingly, click to select do not directly attack, nor destroy, any pathogens.
2. they click to select to pathogens, and in doing so render them incapable of causing an immune response.
3. this opens binding sites and promotes click to select, resulting in a conversion of complement proteins to fight the pathogen.
4. antibodies that bind to more than one cell simultaneously can rapidly cause click to select to occur, which is a clumping that prevents the pathogen from contacting and damaging human cells.
5. this process makes the molecule insoluble and less mobile. this is an example of click to select.

cytotoxic t cells
inflammation
macrophages
bind
agglutination
antibodies
precipitation
complement fixation

Explanation:

1. Antibodies are part of the immune system but do not directly attack pathogens.
2. Antibodies bind to pathogens to neutralize them.
3. Binding of antibodies promotes complement fixation which activates complement proteins.
4. When antibodies bind to multiple cells simultaneously, agglutination (clumping) occurs.
5. Agglutination makes molecules insoluble and less mobile, which is an example of precipitation in the context of antibody - antigen reactions.

Answer:

1. antibodies
2. bind
3. complement fixation
4. agglutination
5. precipitation
