3 ways that antibodies help destroy pathogens?

The antigen itself cannot destroy the pathogen but here are three ways it helps out:

1. Antibodies can clump antigens together in order to enhance phagocytosis

2. Antibodies can activate the cytotoxic cell responses (a chemical that destroys antibody-bound antigen).

3. Antibodies can activate B lymphocytes, which results in the production on plasma and memory cells.
