Assume a cell with the following properties: [Na]out = 120 mM; [Na]in = 12 mM; [K]out = 5 mM; [K]in = 125 mM. The membrane is permeable only to Na+ and K+. If the plasma membrane of the cell becomes more permeable to Na+, both the influx of Na+ into the cell and the Na+ equilibrium potential will increase. Question: Is this true or false and please explain! As sodium is more permeable, it will influx faster than potassium, resulting in an increase in the influx of Na+ into the cell. However, the equilibrium potential for Na+ will not change since there were no additional solutes of sodium added.

During the repolarization phase of the action potential, it is correct to say that the cell's permeability to sodium decreases. The cell's permeability to potassium increases. Both b and c are true. The cell's permeability to sodium increases. Both b and c are true. QUESTION 32 Resting membrane potential is defined as the movement of action potentials along a resting axon.
