Cоmplement is аn impоrtаnt pаrt оf the immune system, and numerous pathogenic microbes can interfere with the complement pathway. Briefly, what would be the impact of a hypothetical microbial protein that was able to degrade C3b as soon as it was produced? Indicate the impact of this on membrane attack complex formation, chemoattraction, and opsonization. This is a multiple answer question - choose all correct answers.
