C3 convertase protects normal cells from lysis by complement.
C3a is a decay-accelerating factor and causes the rapid decay and death of bacteria.
In general, gram-positive bacteria are more likely to be killed by complement than gram-negative bacteria.
The membrane attack complex is formed as a result of activation of the classic pathway but not by activation of the alternative pathway.
