The resting membrane potential is close to the equilibrium potential of which of the following ions? A) sodium (Na⁺) B) potassium (K⁺) C) chloride (Cl ^-) D) calcium (Ca⁺⁺) E) phosphate (PO₄^-)

Question

Quizplus · Accepted Answer

The resting membrane potential is primarily determined by the concentration gradient and permeability of potassium ions (K+), making it close to the equilibrium potential of potassium.
