Antibody Effector Functions — Quiz
Test your understanding of antibody effector functions with 5 practice questions.
Practice Questions
Question 1
Which antibody effector function involves antibodies binding to toxins or viruses to prevent their attachment to host cells?
Question 2
Which Fc gamma receptor has the highest affinity for monomeric IgG and is primarily responsible for antibody-mediated phagocytosis by macrophages?
Question 3
Which complement fragment functions as an opsonin by covalently attaching to bacterial surfaces and enhancing phagocytosis via complement receptors?
Question 4
Among human IgG subclasses, which is most effective at activating the classical complement pathway and mediating ADCC due to its long hinge region and strong Fc receptor binding?
Question 5
During antibody-dependent cellular cytotoxicity (ADCC), natural killer cells recognize antibody-coated target cells through which receptor?
