Question

Some have compared the "all or none" action potential to flushing a toilet.
The absolute refractory period (when no amount of pressing the lever will produce
another flush) is set by:
the inactivation of voltage gated potassium channels
the inactivation of voltage gated sodium channels
the opening of voltage gated sodium channels
the inactivation of voltage gated chloride channels

Expert Solution

Step 1

An action potential is a common pattern of the quick rise and subsequent decline in voltage or membrane potential across a biological membrane. An action potential has three distinct phases: depolarization, overshoot, and repolarization.

There are two other states of membrane potential in addition to the action potential. Hyperpolarization occurs before depolarization, and hyperpolarization occurs after repolarization. A sufficient current is required to cause a voltage response in a cell membrane; if the current is insufficient, the membrane will depolarize to the threshold.
