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

Question

Quizplus · Accepted Answer

The rising phase of the action potential is due to the influx of sodium ions into the cell. This depolarizes the cell membrane and triggers the action potential. Calcium equilibriums play a role in neurotransmitter release and muscle contraction, while potassium efflux and influx are involved in repolarization and hyperpolarization phases of the action potential, respectively.
