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
