torisob [31]

Answer:

True

Explanation:

Tetrodotoxin is the molecules that act as a poison to the organism in which they are injected.

The tetrodotoxin proves lethal to the organisms as it kills the organism by interfering with the nervous system. The tetrodotoxin blocks the sodium channels in the neuron as a result of which the sodium is unable to enter the neurons and hence the electrical impulse is not generated.

If the tetrodotoxin blocks the motor neuron transmission by blocking the sodium channels then the signals will not reach the muscle and muscle will not be able to contract.

Thus, true is correct.
