Which of the following is responsible for the falling phase of an action potential? A)opening of Na⁺ gates B)Na⁺-K⁺ pump restoring the ions to their original locations C) greatly increased permeability to Na⁺ D) opening of K⁺ gates and K⁺ efflux

Question

Quizplus · Accepted Answer

The falling phase of an action potential is due to the opening of potassium (K+) channels and subsequent efflux of K+ ions, which causes the membrane potential to become more negative and the cell to repolarize. The other options listed are not responsible for the falling phase of an action potential.
