The blue-ringed octopus, shown below, utilizes a venom called tetrodotoxin as a defense mechanism.

Tetrodotoxin binds to sodium channels and blocks the passage of sodium ions. Based on this information, which symptom would most likely occur in an organism exposed to tetodotoxin?

A.
decreased appetite due to the production of hormones that indicate fullness
B.
paralysis due to lack of action potentials to signal muscle tissue
C.
increased heart rate due to increased nerve impulses to the heart muscles
D.
blindness due to proteins in the eyes denaturing and losing functionality

)B paralysis. Tetrodotoxin works by inhibiting the firing of action potentials in neurons by binding to the voltage-gated sodium channels in nerve cell membranes and blocking the passage of sodium ions into the neuron. This prevents the nervous system from carrying messages, eventually leading to paralysis

Paralysis due to lack of action potentials to signal muscle tissue- this symptom most likely would occur in an organism exposed to tetrodotoxin.

The symptom occurs in an organism of tetrodotoxin:

Tetrodotoxin is a potent neurotoxin found in pufferfish, porcupinefish and blue-ringed octopus.

Has tetrodotoxin (TTX) in blue-ringed octopuses venom which causes pain and neurotoxic effects(paralysis) by inhabiting signal transduction by nerve cells through sodium channel blockade.

A dose of venom can shut down muscles such as those that keep you breathing and cause death within 30 minutes.

The correct answer is option B.
