A protein named Membrane Cofactor Protein (MCP) cleaves C4b into C4c and C4d, effectively blocking any pathway dependent on C4. Which of the following pathways can still proceed? Group of answer choices None of the above. Classical Pathway. Alternative Pathway. Lectin Pathway.

Step 1
C4 is a component of the classical and lectin pathways of the complement system. It is cleaved into C4b and C4a, with C4b further cleaved into C4c and C4d by MCP. Show more…

Which of the following is NOT involved in the classical complement pathway? Group of answer choices Formation of C3 Convertase via C4b-C2a Formation of a membrane attack complex Activation of MASP's, resulting in C2 and C4 cleavage All of these are involved with the classical complement pathway. Production of anaphylatoxins such as C3a

QUESTION 13 Which of the following statements about the complement pathways is FALSE? They are all part of the innate immune response. They are all activated at the same time starting from 0 - 4 hours. They all form C3b which binds to the pathogen surface. They all initiate the formation of the membrane attack complex. QUESTION 14 Which of the following choices shows the complement pathways in their correct order of activation? classical pathway ; alternative pathway ; mannose-binding lectin pathway classical pathway ; mannose-binding lectin pathway ; alternative pathway alternative pathway ; mannose-binding lectin pathway ; classical pathway mannose-binding lectin pathway ; classical pathway ; alternative pathway ; QUESTION 15 If an individual was deficient in the CD59 protein, what could happen during a bacterial infection? pathogens would not be tagged with C3b no C3 convertase would form at the host cell surface membrane attack complexes could form on host cell surfaces macrophages would be unable to phagocytose the invading pathogens

While the lectin and classical complement pathways use a different "set" of complement proteins than those used in the alternative pathway, several of the molecules used in the lectin and classical complement pathways share structural and functional similarities to alternative complement pathway molecules. Match each of the given alternative complement pathway components with the equivalent component used in the lectin/classical complement pathways:
