A) Many processes are involved in creating the “Resting membrane potential.”  Describe the ion and concentration “FORCES” / “PROCESSES” that are involved in determining the resting membrane potential.

B)  Chambers A and B are separated by a membrane.  Chamber A contains 7.22 M KNO3 and chamber B contains 3.89 M KNO3.  If K+ is in equilibrium across the membrane, what is the electrical (potential) difference (Resting membrane potential)? Which side is electrically positive?
