Many bacterial toxins are composed of a receptor-binding subunit and a biologically active subunit. Neutralizing antibodies against toxins like tetanus toxin and cholera toxin work how? 1. Antibody binds to the host cell receptor for the toxin, preventing entry 2. Antibody binds to the part of the toxin recognized by the host receptor, thereby preventing entry 3. Antibody binds to the biologically active component of the toxin, preventing it from acting 4. Antibody binds to the surface of the pathogenic bacteria, preventing release of the toxin
