STX Case Study

Satisfactory Essays

4. Saxitoxin (STX) is a neurotoxin that blocks neural transmission by binding to the voltage-gated Na+ channel. When bound to the voltage-gated Na+ channel, STX inhibits the permeability of Na+ ions, which are responsible for depolarizing the membrane. Since STX keeps the membrane from depolarizing, the resting membrane potential would remain the same.
