Quizplus · Accepted Answer

Hemolysins are not AB toxins. AB toxins consist of two components: the A component, which is toxic and the B component, which binds to specific receptors on host cells and delivers the A component inside the cell. Hemolysins are not composed of separate A and B components but instead act as cytolytic toxins by forming pores in host cell membranes. The other options listed are examples of AB toxins: shiga-like toxin, botulinum toxin, and tetanus toxin.
