At rest, a neuron has a lower concentration of sodium than the surrounding fluid. The neuron also has a higher concentration of potassium inside the cell. The sodium-potassium ion pump is used to maintain the neuron in the resting state. Which of the following statements is true? A. Remaining at rest requires the use of ATP. B. Remaining at rest requires an input of sodium. C. Remaining at rest requires the activation of cotransporters. D Remaining at rest requires decreased permeability of the membrane.

Mark the following statements as true or false. If a statement is false, correct it to make a true statement. a. The resting membrane potential refers to the voltage difference across the membranes of excitable cells at rest. b. The concentration of Na+ is highest in the cytosol, and the concentration of K+ is highest in the extracellular fluid. c. The Na+>K+ pumps and gated channels maintain the Na+ and K+ gradients necessary for action potentials to occur. d. A depolarization is a change in membrane potential that makes the potential less negative. e. A local potential is a change in membrane potential that conducts the long-distance signals of the nervous system

The resting membrane potential of a cell is the consequence of which of the following concentrations of ions? A. High K* and Cl- outside the cell and high Na* and large anions inside the cell. B. High K* and Na* outside the cell and high Cl- and large anions inside the cell. C. High Cl- and Nat outside the cell and high K* and large cations inside the cell. D. High Ca2+ and Nat outside the cell and high K* and large cations inside the cell.
