Homework Answers
Ans: The correct option is C (Type III toxin).
A-B toxin interfere with cell function. The A component of A-B toxin catalyze reaction in which ADP-ribosyl group is removed from coenzyme NAD and this group is attached to host cell protein. This interfers with the normal functioning of cell.

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

QUESTION 27 These unusual bacterial toxins interact with and activate exceedingly large numbers of T-lymphocytes resulting in excessive production of IL-2. This, in turn, can lead to production of inflammatory cytokines such TNF-alpha, IL-1, inflammatory chemokines such as IL-B, and platelet-activating factor or PAF, and potentially lead to SIRS. This best describes what? Type Il toxins that interfere with host cell functions Type I toxins (superantigens) Bacterial endotoxin Type Il toxins that damage cell membranes Promiscuous slut toxins
