← Nature & AnimalsWhich outcome arises when a honeybee stinger, left embedded in a victim, continually pumps venom?
A)Disrupted sodium-potassium channel membrane polarization✓
B)Localized histamine reduction reverses envenomation
C)Neutralization of metalloprotease-induced tissue damage
D)Epinephrine blocks neurotransmitter autonomic response
💡 Explanation
Continued venom pumping causes increased local concentration; therefore, disrupted sodium-potassium channel membrane polarization occurs via phospholipase A2, because it specifically blocks ion transport rather than general histamine or protease effects.
