WebAn action potential would not occur because an action potential in an axon cannot be initiated without voltage-dependent Na + channels. How would TEA affect the action potential? It would be longer and would not have an undershoot. WebWhy does the action potential have an undershoot after hyperpolarization )? As a result, potassium continues to flow out of the cell even after the membrane has fully repolarized . Thus the membrane potential dips below the normal resting membrane potential of the cell for a brief moment; this dip of hyperpolarization is known as the undershoot. super cario world - jungle runnerWebThe Action Potential Resting membrane potential describes the steady state of the cell, which is a dynamic process that is balanced by ion leakage and ion pumping. Without any outside influence, it will not change. To get an electrical signal started, the membrane potential has to change. This starts with a channel opening for Na + in the membrane. super cario world

The voltage-gated potassium channels stay open a little longer than needed to bring the membrane back to its resting potential. This results in a phenomenon called “undershoot,” in which the membrane potential briefly dips lower (more negative) than its resting potential. ...
