Compare the impact on an organism treated with a drug that blocks neuronal sodium channels versus potassium channels.
What will be an ideal response?
The drug that blocks sodium channels would cause rapid death, owing to the cessation of action potentials. The organism would experience a similar fate after taking a drug that blocks potassium channels, as potassium would not be able to leave the cells when necessary, creating a depolarizing force within the cells that cannot be counteracted.
