Question

The ________ is the difference in charge between the intracellular and extracellular space of a neuron. extracellular fluid intracellular fluid membrane potential resting potential

Answer 1

The answer to this question is membrane potential 

The gradient of electrolyte concentration from inside cell and outside cell will determine the membrane potential. Natrium or sodium is much higher outside the cell than inside cell. In contrast to the sodium, potassium is much more inside cells. This two electrolyte have major role in the membrane potential and action potential. 

Answer 2

The answer is membrane potential

Further explanation

Membrane potential (ΔΨ) is the difference in electrical potential between the outer and inner walls of a cell membrane that ranges from about -50 to -200 millivolts (a minus sign indicates that the inside of a cell is negative compared to the outside). All cells have a voltage across their plasma membrane, where the voltage is the electrical potential energy-the opposite charge separation. Cytoplasmic cells are negatively charged compared to extracellular fluid caused by the distribution of anions and cations on opposite sides of the membrane that are not the same. The membrane potential acts like a battery, an energy source that influences the traffic of all charged substances that cross the membrane. Because inside the cell is negative compared to outside, the potential of this membrane supports passive transport of cations into cells and anions out of cells. Thus, the two forces move the diffusion of ions across a membrane: the chemical force (gradient of ion concentration) and the electric force (the potential influence of the membrane on the movement of ions). The combination of the two forces acting on one ion is called an electrochemical gradient. Changes in the environment can affect the membrane potential and the cell itself, for example, depolarization of the plasma membrane is thought to trigger apoptosis (programmed cell death).

Membrane potential is the result of differences in the concentration of potassium and sodium between cell membranes maintained by ion intake. Most of the body's energy expenditure at rest is devoted to maintaining membrane potential, which is very important for the transmission of nerve impulses, muscle contraction, heart function, and nutrient transportation and metabolites into and out of cells.

The phenomenon of transporting ions across the membrane and efforts to maintain levels of certain ions inside the cell differ from those outside the cell, resulting in a difference in charge distribution between the inside of the membrane bordering the intracellular fluid and the outer part facing the extracellular fluid.
