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 become less negative.
C)The membrane potential would remain the same.

Increasing the intracellular concentration of K⁺ will cause the inside of the cell to become more positive, since K⁺ is a positively charged ion. This will make the membrane potential less negative, since the inside of the cell will be less negative relative to the outside.
