The membrane potential in which there is no net movement of the ion across the membrane is called the ________.
A) graded potential
B) threshold potential
C) equilibrium potential
D) action potential
E) inhibitory postsynaptic potential

Question

Quizplus · Accepted Answer

The equilibrium potential is the membrane potential at which the electrical and chemical gradients across the membrane are balanced, and there is no net movement of the ion across the membrane. This occurs when the chemical force (concentration gradient) pushing the ion across the membrane is equal and opposite to the electrical force (membrane potential) pushing the ion in the opposite direction. The other choices (graded potential, threshold potential, action potential, and inhibitory postsynaptic potential) all refer to different types of membrane potentials that are involved in generating and transmitting signals in neurons.
