Wish u could solve it soon.
Thanks
BIOL 240 Human Phys Quantitative Questions-2 Fall 2017-v4 [Compatibility Mode] Q Search in Document Home InsertDesign Layout References Mailings Review View Quantitative Questions 2- Nervous System 1. High or low potassium and equilibrium potential and membrane potential: The equilibrium potential (E for an ion (e.g., K+), as you may recall, is the membrane potential at which electrical and chemical drivine forces are balanced and there is no net flow of the ion. The equilibrium potential for potassium (Eor V) can be calculated using the Nernst Equation: RT General eq for Potassium(+D)F [K' The equilibrium potential will change depending on the concentration of potassium inside and outside the cell. Sometimes physiologist will change the concentration of potassium outside (IK lo) the cells to induce effects in the cells under study, What effect would changing [lo have on the equilibrium potential? 1.1 Usine the Nernst Potential/Equilibrium Potential calculator on the physiology web enter values into the table below and answer the questions below. Use the following values in the calculator: T-310 K z-1, XInK -150 mM, Set the output ( to mv rather than V [K lo (mM) 1 Ee/V(mV) 2.5 10 1.2 What happens to EV as the concentration of potassium increases? Describe the relationship in words and plot the data on the chart below (or make your own and attach it) Page 1 of 2 417 Words English (US) 104%
