Which of the following is correct in case of active membrane potential?

Explanation

Option A: This is true at rest, but not during an action potential. During an action potential, the concentration of sodium ions outside the cell actually decreases slightly, as some sodium ions are drawn into the cell.. Option B This is false at both rest and during an action potential. The concentration of potassium ions outside the cell is always much lower than the concentration of potassium ions inside the cell. Option C and D: The correct answer is intracellular sodium is high and intracellular potassium is less. In a resting cell, the membrane potential is negative, meaning that there are more negatively charged ions inside the cell than outside. This is because the cell membrane is more permeable to potassium ions than sodium ions. Potassium ions are therefore more likely to diffuse out of the cell, while sodium ions are less likely to diffuse in. During an action potential, the cell membrane becomes more permeable to sodium ions. This causes sodium ions to rush into the cell, which depolarizes the membrane and creates an action potential. After the action potential, the cell membrane returns to its resting state. This is because the sodium channels that were open during the action potential close, and the potassium channels open. This allows potassium ions to diffuse out of the cell, which repolarizes the membrane. Therefore, in a cell that is experiencing an action potential, the intracellular sodium will be high and the intracellular potassium will be low.
