Homework Answers
In this case, the correct answer is Shiga Toxin. This toxin contains two subunits (A and B). The B subunit binds to specific glycolipids on the host cell while the A subunit will be internalized and then cleavage into two domains. A1 will be able to bind to the rRNA and inhibits protein synthesis.

QUESTION 3 A number of bacteria produce these type ill toxins that bind to the cells of the small intestines. Most of these toxins catalyze the ADP-ribosylation of host cell proteins that turn the synthesis of the metabolic regulator molecules cyclic AMP (AMP) or cyclic GMP on and off in intestinal mucosal cells. High levels of CAMP and CGMP cause loss of electrolytes and water resulting in diarrhea. Enterotoxin Botulism exotoxin Pertussis exotoxin Shiga toxin Diphtheria exotoxin
