Problem 10 - Consider an ion channel that open with membrane tension of 10 pNm. If the change in membrane area is 2 an, what is the corresponding change in free energy when the channel transition from closed to open? - How does this change in free energy compare with kBT? - If the equilibrium constant for this transition (equilibrium = in the absence of force) is keq=0.015, what is the corresponding ratio between open and closeed states
