Question

The year is 2200, and the intrepid space explorer Joel E. has been bitten by some kind of toothy alien. We don't know much about the alien, but we do know its venom causes voltage-gated potassium channels to close even slower than normal.

You tell Joel to expect...
T
[Choose ]
His neurons will be incapable of graded potentials
It will take larger-than-usual threshold stimuli to trigger action potentials
YES
His neurons will be incapable of action potentials
The magnitude of each of his action potentials will be smaller

Expert Solution

Step 1: Voltage gated potassium channels

Voltage gated potassium ion channels are transmembrane channels that play a very important role during the nerve impulse conduction. When the nerve impulse has been conducted or an action potential has already been performed the opening of potassium gated ion channels allows the loss of potassium ions from inside of the cell to outside thereby returning the positive potential to negative potential of the resting membrane level.
