Antibodies and Complement are Both Protein Molecules That are Important

Question

Antibodies and complement are both protein molecules that are important in the immune system.

Accepted Answer

Antibodies and complement are indeed protein molecules that are essential components of the immune system. Antibodies are produced by B cells and neutralize pathogens by binding to their surface antigens, whereas the complement system consists of a series of proteins that can be activated in response to infection and work together to eliminate pathogens by various mechanisms such as opsonization, membrane attack complex formation, and inflammation.
