Which of these would occur if the concentration of ATP were depleted in a typical nerve cell? A) Resting membrane potential would become more negative. B) Resting membrane potential would become less negative. C) The concentration gradient for Na⁺ would remain the same. D) The resting membrane potential would eventually become positive inside with respect to outside. E) There would be no change in the resting membrane potential.

ATP is required for the function of the sodium-potassium pump which maintains the concentration gradient of Na+ and K+. Without sufficient ATP, the pump would not function properly, leading to a higher concentration of sodium ions inside the cell and lower concentration of potassium ions. This would lead to a less negative resting membrane potential in the nerve cell.
