The venom of a puffer fish (tetrodotoxin) stops voltage-gated sodium channels from functioning. Thus, you would expect a cell treated with tetrodotoxin to:
a. Produce stronger than normal action potentials
b. Produce action potentials quicker
c. To be unable to produce action potentials
d. To be able to depolarize but not repolarize
