Question

Quizplus · Accepted Answer

Complement proteins can bind to the surface of parasites and activate a cascade of reactions that can lead to the formation of a membrane attack complex (MAC), which can lyse the parasite. This mechanism is effective against larger parasites that cannot be engulfed by phagocytosis. T helper cells, B cells, macrophages, and basophils are all involved in the adaptive immune response and are more effective against smaller pathogens that can be engulfed by phagocytosis.
