QUESTION 3 The Nernst Equation describes the equilibrium potential for any ion that is necessary to balance a given ionic concentration gradient across a membrane so that the net flux of the ion is zero. lons [Intracellular fluid), mmol/L [Extracellular fluid), mmol/L Na+ 15 145 K+ 150 5 CI 100 7 3.1 (7) 3.2 Assume the ions in the table above are at a temperature of 37°C, then determine the equilibrium potential for sodium, potassium, and chloride ions, respectively. Show all your calculations. If the concentration of sodium inside changes to 135 mmol/L. What effect will it have on the equilibrium potential of all ions if the temperature remains the same? Indicate "increase/decrease/remain the same” next to your answer. Motivate your answer where necessary. (3) [10]
