Hi........


An organism exposed to tetrodotoxin would most likely to Paralysis due to lack of action potential in neurons to signal muscle tissue. Tetrodotoxin is a sodium channel inhibitor. It is a potent neurotoxic substance. The toxin binds to the sodium ion channels and inhibits the entry of sodium ions into the neuron. This prevents the muscle response stimulated by the nervous system. Death may occur in case of severe poisoning of tetrodotoxin.


Hope it helped.

D. paralysis due to lack of action potentials to signal muscle tissue

Explanation:

  • Tetrodotoxin is a poisonous substance which affects the transmission of signals in the neurons.
  • The tetrodotoxin affects neurotransmission by binding to the voltage-gated sodium channels which inhibit the entry of the sodium channels inside the neurons.
  • Due to this, the depolarization of neuron does not take place and the action potential is not generated.
  • This action is observed when the nerves carrying the signals are blocked in the nerve which carries the signals from the brain to the muscle.
  • Since the muscles do not receive the signals therefore the paralysis condition is observed.
