Question

Scorpion agitoxin is a neurotoxin that blocks the activity of voltage-gated potassium channels. In the presence of agitoxin, which will occur during an action potential?

Answer 1

Answer:

The neurons are unable to repolarize.

Explanation:

The cell membrane potential remain negative at the resting membrane potential. The potassium channels maintains the negative voltage inside the cell and makes the cell stable at resting membrane potential.

The scorpion agitoxin affects the potassium channels, the depolarize cell remains in the depolarize state because potassium channels are inhibited. The cells are unable to repolarize as the potassium channels are unable to enter in the cells.
