Final answer:
Cholera, tetanus, and diphtheria produce exotoxins, specifically tetanus produces a neurotoxin, cholera an enterotoxin, and diphtheria toxin inhibits protein synthesis leading to cell death.
Step-by-step explanation:
Cholera, tetanus, and diphtheria produce toxins that fall into the category of exotoxins. Specifically, diphtheria toxin, produced by Corynebacterium diphtheriae, inhibits protein synthesis and ultimately leads to cell death. The tetanus toxin, produced by Clostridium tetani, is a neurotoxin that interferes with the release of inhibitory neurotransmitters, causing spastic paralysis. Cholera toxin, produced by Vibrio cholerae, is an enterotoxin that disrupts the normal physiology of intestinal epithelial cells, leading to severe diarrhea.
