Complement proteins and antibodies coat a microorganism and provide binding sites,enabling macrophages and neutrophils to phagocytize the organism.This phenomenon is termed ________.
A) opsonization
B) agglutination
C) diapedesis
D) chemotaxis

Question

Quizplus · Accepted Answer

Opsonization is the process of coating microorganisms with complement proteins and antibodies, which provide binding sites for macrophages and neutrophils to phagocytize the organism. Agglutination refers to the clumping of microorganisms, diapedesis is the process by which white blood cells leave the bloodstream and enter tissues, and chemotaxis is the movement of white blood cells towards a chemical gradient. None of these processes specifically refer to the coating of microorganisms with complement proteins and antibodies.
