C3 convease acts on

The complement system consists of plasma proteins that play an impoant role in host defence (immunity) and inflammation. the critical step in the generation of biologically active complement products is the activation of C3 C3 cleavage occurs by three pathways: classical pathway, the alternative pathway, lectin pathway, All three pathways lead to the formation of a C3 convease that cleaves C3 to C3a and C3b.
