The Depolarization Phase of an Action Potential Is Punctuated by the Closing

question 50

Multiple Choice

The depolarization phase of an action potential is punctuated by the closing of inactivation gates in the voltage gated sodium ion channels. All of the following are consequences of this inactivation except one. Choose the statement below that is not a consequence of the closing of inactivating gates.

• A) This allows for the one way transmission of action potential down the axon.
• B) This allows for the efflux (diffusion out) of potassium ions, resulting in the repolarization of the cell.
• C) This limits the frequency of action potentials down the axon.
• D) This stops the depolarization of the axon membrane.
