Indicate True (T) and False (F) Statements Below Regarding the Complement

Short Answer

Indicate true (T) and false (F) statements below regarding the complement system. Your answer would be a four-letter string composed of letters T and F only, e.g. TTFT.
( ) The early complement components form the membrane attack complex, whereas the late complement components cleave and activate C3.
( ) The classical pathway of complement activation is triggered by binding of a secreted PRR to mannose-containing glycoproteins or glycolipids on the surface of pathogens.
( ) Some pathogens such as Neisseria gonorrhoeae hide from the complement reaction via sialic acid camouflage.
( ) Once a membrane attack complex is formed, it can attack multiple pathogens before becoming inactivated.
