Increased permeability to what ion is responsible for the relative refractory period? A) sodium (Na⁺) B) potassium (K⁺) C) chloride (Cl ^-) D) calcium (Ca⁺⁺) E) phosphate (PO₄^-)

Question

Quizplus · Accepted Answer

The relative refractory period is characterized by an increased permeability to potassium ions (K+), which occurs as the membrane is returning to its resting state and is more difficult, but not impossible, to excite.
