1. Chemical Potential a. The concentration of sodium ions across a permeable membrane is 50m M and 100m M . Find the difference in chemical potential. What units is it in? b. The concentration of sodium ions across a permeable membrane is 50mM and 100mM. The concentration of potassium ions is 50mM and 25mM. What is the difference in chemical potential for each ion. c. The difference in chemical potential across a permeable membrane is 1kJ, the higher concentration side has a concentration of 10m M , what is the concentration on the lower side? d. A permeable membrane divides two chambers of volumes 1L and 2L. If 1 mmol of ions are placed in the 1L side, what is the difference in chemical potential across the membrane initially? How many moles of ions are on each side at equilibrium? 2. Equilibrium a. A protein only binds to a ligand in its dimeric form. Write out the reaction in terms of reactants going towards products (no peaking!) b. An interaction between two proteins A + B AB occurs. A test tube with 1mL of
