← Nature & AnimalsWhich mechanism explains prey paralysis following spider envenomation?
A)Inhibition of postsynaptic acetylcholine receptors✓
B)Venom-mediated ATP production escalation
C)Enhanced neuronal action potential propagation
D)Accelerated muscle fiber glycogen synthesis response
💡 Explanation
Acetylcholine signals are normally required for muscle contraction; however, curare-like toxins in venom block acetylcholine receptors through competitive inhibition, causing paralysis because this prevents muscle activation rather than enhanced or diminished energy processes requiring ATP.
