Vibrio cholerae is the bacterium which causes the disease cholera. Vibrio cholerae is a toxigenic bacterium, meaning it creates toxins. The toxin created by Vibrio cholerae is and A-B toxin which disrupts the ionic balance of the host's intestinal cell membranes. This results in vomiting, diarrhea, and severe dehydration in infected individuals which could lead to death. The toxin created by Vibrio cholerae is an A-B toxin and a _________ toxin.

The components which make up an exotoxin are:

Even though chemotherapy is used as a treatment for cancers it also causes cellular damage. Chemotherapy drugs possess toxins that attempt to target and destroy rapidly dividing cells, such as tumor cells. The toxins found in chemotherapy drugs are _________.

Anthrax is a serious illness caused by the Bacillus anthracis bacteria. The Bacillus anthracis bacteria create a dangerous toxin composed of three protein parts. Each individual part of the toxin does not cause symptoms of disease. However, when the three parts are combined, the toxin causes disease. Scientists know that one part of the toxin allows attachment to the host cells while the other two parts cause disease. The anthrax toxin is an example of a ____ toxin.  

Botox is a common, temporary cosmetic treatment. Botox injections use the botulinum toxin created by Clostridium botulinum bacteria to block certain nerves and paralyze muscles of the face to reduce the appearance of facial wrinkles. The botulinum toxin is an example of which type of toxin?

Eisenia fetida is a species of earthworm which creates the lysenin toxin. The toxin defends the worm against infectious bacteria and fungi. The lysenin toxin forms pores in the membranes of pathogens which leads to apoptosis of the pathogens. The lysenin toxin is a _________.
