Although bacterial toxins vary in their activity and effects on host cells, a small amount of gram-negative bacteria endotoxin:
A) Is released during cell growth
B) Inactivates key cellular functions
C) Uses protein to activate enzymes
D) In the cell wall activates inflammation
Ans: D
Feedback:
Endotoxins differ from exotoxins in several ways. Endotoxins are found in the cell wall lipids of gram-negative bacteria and are potent activators of life-threatening systemic responses such as acute inflammation with clotting and hypotension. Exotoxins contain protein, are released during cell growth, inactivate key cell functions, and have enzymatic activity.
