The process by which antibodies bind to specific sites on bacterial exotoxins (toxic chemicals secreted by bacteria) to block their harmful effects is called ________.
A) agglutination
B) chemotaxis
C) complement fixation
D) neutralization
E) precipitation

Question

Quizplus · Accepted Answer

The process described is called neutralization, in which antibodies bind to specific sites on exotoxins to prevent them from causing harm. Option A (agglutination) involves the clumping of cells in response to antibodies, while option B (chemotaxis) refers to the movement of cells towards or away from a chemical signal. Option C (complement fixation) is the activation of the complement system by antibodies to destroy pathogens. Option E (precipitation) involves the formation of insoluble complexes between antigens and antibodies.
