A research scientist is interested in the effects of various toxins on the action potential in nerve cells. During one of the electrophysiological tests, the scientist injects tetrodotoxin (TTX) into the bathing solution. Which aspect of the action potential will most likely be affected by the injection of TTX?
A) Depolarization due to K+ channel blockade B) Depolarization due to Na+ channel blockade C) Depolarization due to Na+ channel opening D) Hyperpolarization due to K+ channel blockade E) Hyperpolarization due to Na+ channel blockade
