action potential1 Action potential/ Muscle contraction action potential The action potential causes a change in potential as ions are temporarily exchanged in the cell membrane when muscles and nerves are excited. Na+ and K+ ions present in the cell membrane differ in their ionic composition in and out of the cell by the action of the pump. Due to this compositional difference, measuring the inside of the cell membrane with a voltmeter shows a poten.. 2021. 8. 26. 이전 1 다음
