If you experimentally increase the concentration of K⁺inside a cell, while maintaining other ion concentrations as they were, what would happen to the cell's membrane potential? A) The membrane potential would become more negative. B) The membrane potential would remain the same. C) The membrane potential would become less negative.

Question

Quizplus · Accepted Answer

Increasing the concentration of positively charged ions inside the cell would result in a decrease in the membrane potential, as the inside of the cell becomes less negative relative to the outside. This is because the positive charge inside the cell would attract negative ions outside the cell, which would tend to make the outside of the membrane more positive and the inside more negative. Therefore, the correct answer is C: the membrane potential would become less negative.
