B) requires the activity of voltage-gated ion channels. C) is due to electrochemical gradients. D) is equivalent to the resting potential. E) was discovered through patch clamping.

Question

Quizplus · Accepted Answer

The potassium equilibrium potential is due to electrochemical gradients, as it takes into account both the concentration gradient and the negative electric potential across the membrane. This balance is achieved without the need for voltage-gated channels, and it may or may not be equivalent to the membrane potential or resting potential depending on the specific ion conductances and permeabilities involved. Patch clamping is a technique used to study ion channels, but it is not directly related to the concept of equilibrium potentials.
