The falling phase of the action potential is due to which of the following conditions?
A)calcium equilibrium
B)potassium efflux
C) potassium influx
D) sodium efflux

Question

Quizplus · Accepted Answer

The falling phase of the action potential is due to the potassium efflux, i.e., outward flow of potassium ions from the cell. As the PMP moves towards the resting potential, the voltage-gated potassium channels remain open, causing an outflow of potassium ions, which brings the potential back towards the resting level.
