Palytoxin is incredibly toxic, perhaps the second most dangerous nonpeptide toxin. It targets the sodium-potassium pump, locking it open and forming a channel through which the ions can passively flow. Palytoxin is produced by zoanthid cnidarians (soft coral), and there have been incidents of poisoning from zoanthids within marine aquaria tanks in people's homes. It is also thought to be the source of the legend of the Limu make o hana ("Seaweed of Death from Hana").What is the likely impact of this toxin on the resting potential of a neuron?
A. The resting potential will promote action potentials with a larger depolarization.
B. The resting potential will be more negative.
C. The resting potential will require more energy to maintain.
D. It will destroy the ion gradients necessary for the resting potential.
