The concentration of a negative ion is 100 mMoUL extracellular and 10 mMo1/1 intracellular. What will be the Nernst potential for this ion?
Correct Answer: --61 mV
Description: Ans: C. --61 mVRef: Ganong 25Ie p9, p24Ie p9-10; Guyton 13Ie p61Ek = 61.5 log Ci/CeIntracellular concentration Ci = 100Extracellular concentration Ce = 10EK = 61 C log100/10 = -61 mV.
