Question

Quizplus · Accepted Answer

The complement pathway activated by mannan-binding protein is the lectin pathway. Mannan-binding protein binds to certain carbohydrates on the surface of pathogens, which triggers a cascade of reactions leading to activation of the lectin pathway. This is distinct from the classical and alternative pathways, which are triggered by different stimuli.
