Final answer:
The toxin produced by Vibrio cholerae does not inhibit protein synthesis. It is an enterotoxin and exotoxin that increases cyclic AMP (cAMP) levels and causes diarrhea.
Step-by-step explanation:
The characteristics of the toxin produced by Vibrio cholerae, the bacterium that causes cholera, do not include the ability to inhibit protein synthesis. Cholera toxin is an enterotoxin and an exotoxin composed of a protein complex, including one A subunit and five B subunits. This toxin's primary action is to bind to intestinal epithelial cells and increase cyclic AMP (cAMP) levels, leading to the secretion of large amounts of fluids into the intestinal lumen, causing severe diarrhea. The toxin does not inhibit protein synthesis, which is a characteristic of some other bacterial toxins but not the one produced by Vibrio cholerae.
