Question

How do antibodies make antigens useless?

Answer 1

A) This process is called "Neutralisation" and can lead to Opsonisation. Its basically the process where antigens bind and surround the antigen in like a mesh. Much like wrapping lots of paper around a ball

The reasons the antibody binds only to the antigen is that the structure of the antibody has a "head" with a composition that only bonds to the antigen
