A) action potential.
B) electrochemical gradient.
C) membrane potential.
D) threshold.
E) resting potential.

Question

Quizplus · Accepted Answer

The two forces acting on an ion through an ion channel are the concentration gradient and voltage difference across the membrane. Together, these forces are known as the electrochemical gradient.
