Question

The complement system produces: (select all that apply) Opsonins, proteins that facilitate phagocytosis Proteins that create holes in target cell membranes Antibodies, proteins that bind specific antigens Stomach acid that kills most microbes that are ingested Chemotaxins, proteins that recruit phagocytes Cilia that sweep mucous and particles out of airways Sebum that conditions the skin making it less hospitable for microbes

Answer 1

Opsonins the proteins that facilitate phagocytosis

Proteins that create holes in target cell membranes

Chemotaxins proteins that recruit phagocytes.

This is a complicated system but basically involves these complement proteins recognising some substances that only occur in bacteria. When they are detected, they attach to the bacteria and punch holes in the walls of it, causing the bacteria to burst.
