Which term refers to a special type of antibody that neutralizes bacterial exotoxins?
A
Antitoxin
B
Agglutinin
C
Immunogen
D
Opsonin
Verified step by step guidance1
Understand the key terms related to antibodies and immune responses: an antitoxin is a type of antibody that specifically neutralizes toxins produced by bacteria, called exotoxins.
Recall that exotoxins are harmful proteins secreted by certain bacteria that can cause damage to the host, and the immune system produces antibodies to counteract these toxins.
Recognize that an antitoxin binds to the bacterial exotoxin, neutralizing its harmful effects and preventing it from interacting with host cells.
Differentiate antitoxins from other terms: agglutinins cause clumping of cells, immunogens are substances that provoke an immune response, and opsonins enhance phagocytosis but do not neutralize toxins directly.
Conclude that the term 'antitoxin' correctly describes the special antibody that neutralizes bacterial exotoxins.
