During what phase of the action potential will calcium ions enter the contractile cell as potassium ions exit?

Question

Quizplus · Accepted Answer

During the plateau phase of the action potential, calcium ions will enter the contractile cell through L-type calcium channels, while potassium ions exit through delayed rectifier potassium channels. This balance of ions maintains the depolarized state of the cell and allows for sustained muscle contraction.
