Different Concentrations of Ions on Either Side of a Cell $\rightarrow$

Short Answer

Different concentrations of ions on either side of a cell membrane constitute a concentration cell, which is described by the Nernst equation given below.A cell must expend energy to maintain this concentration gradient by moving ions from one side of the membrane to the other.How much energy must be expended to transport 1 mole of sodium ions across a membrane when the sodium ion concentration is 0.10 M on one side of the membrane and 0.010 M on the other side, and the temperature is 37°C body temperature)?
(Given: Na ⁺ +e ^- $\rightarrow$ Na, Eº_red= -2.71 V; F = 96,485 C; 1 J =1 C V; R = 8.315 J / mol K)) = E° - InQ
