Choose from the following to complete the statements: voltage-gated sodium channels, voltage-gated potassium channels, voltage-gated calcium channels, acetylcholine, acetylcholine esterase, acetylcholine-gated sodium channelsTetrodotoxin is a potent neurotoxin of several blowfish species. affected prey are quickly paralyzed by the toxin which prevents the initiation of action potentials in the pre-synaptic axon. based on this description, tetrodotoxin most likely inhibits the function of .

Voltage gated sodium channel

Explanation:

Voltage gated sodium channel are important for nerve impulse conduction, they are responsible for depolarization that facilitates stroke of action potentials in neurons. Any debilitating of this activity by tetrodotoxin can cause paralysis of the muscle which can lead to respiratory arrest if the respiratory tract is paralysed by tetrodotoxin.

VOLTAGE-GATED SODIUM CHANNELS

Explanation:

Tetrodotoxin acts by binding to the voltage- gated sodium channel in the cell membranes thereby preventing the firing of action potentials in neurons and blocking of the entry of sodium ions into the neurons.

Sodium ions are responsible for the initial rising of the action potential of the nerve cells. Muscles will therefore not contract as a result of block in the passage of message to the nervous system.
