1
Q

2
Q
Classical pathway
A
Complement system activation by the formation of antigen-antibody complexes.
3
Q
Alternative pathway
A
spontaneous complement system activation on pathogen cell surfaces
4
Q
Lectin binding pathway
A
Complement system activation by polysaccharide residues on pathogens
5
Q
Membrane attack complex (MAC)
A
The terminal components of complement that form pores in the membranes of target cells
6
Q
Opsonin
A
An agent that binds to an antigen to tag it for phagocytosis
7
Q
