D)sodium/calcium

Question

Quizplus · Accepted Answer

During a state of polarization, there are more positively charged ions outside the cell compared to inside. Therefore, sodium ions (which are positively charged) are abundant outside the cell, and potassium ions (which are also positively charged) are abundant inside the cell. This is known as the sodium-potassium exchange pump. Therefore, the correct choice is C (sodium/potassium).

During a State of Polarization, ____ Ions Are Abundant Outside
