Question

Quizplus · Accepted Answer

Opsonization is the process in which an antigen (such as a bacterium) is coated with antibodies, making it more easily recognized by phagocytic cells for engulfment and destruction. This process does not involve the membrane attack complex or the complement cascade specifically, although complement can assist in opsonization by facilitating the binding of antibodies to the antigen.
