influx of Cl- Question 60 (3 points) Which of the following is FALSE regarding cellular membrane potentials? The resting membrane potential is determined mainly by the concentration gradients and differential permeability of the plasma membrane to inorganic ions. In their resting state, neurons and muscle cells exhibit a negative membrane potential. The resting membrane potential is maintained by only passive transport processes. In many cell types the resting membrane potential is in part maintained by the sodium-potassium pump.
Sri K.
Which is true about resting membrane potential? This potential is maintained by the unequal distribution of ions on the two sides of the membrane. Potassium is more concentrated inside the cell. Sodium is present in higher concentrations outside the cell. All are true. The sodium-potassium pump plays a role in maintaining the difference of sodium and potassium concentration inside and outside the cell. None.
Which statements are true? Explain why or why not. The membrane potential arises from movements of charge that leave ion concentrations practically unaffected, causing only a very slight discrepancy in the number of positive and negative ions on the two sides of the membrane.
