6 Questions
What is the major proteolytic fragment of C3 that becomes covalently attached to microbes and is able to recruit and activate downstream complement proteins on the microbial surface?
C3b
What is the process called when a microbe is coated with molecules that are recognized by receptors on phagocytes?
Opsonization
What is the function of some proteolytic fragments of complement proteins, especially C5a and C3a, in host defense?
Inflammation
What triggers the alternative pathway of the complement system?
Microbial surfaces
Which pathway of the complement system is initiated by a microbial product in the absence of antibody?
Lectin pathway
What is the function of activated complement proteins?
To function as proteolytic enzymes
