Answer

The complement proteins complements different cells of the immune system. They were named depending on the three pathways, classical, alternative, and lytic pathways. The classical pathway involves complement components C1, C2 and C3. The alternative pathway involves various factors such as B, D, H, and I. The lytic pathway is initiated by C5 splitting ad attachment to C5b. C6, C7, and C9 then unite with C5b.
