An ion-channel is a transmembrane protein that can be in one of two states: OPEN (which allows ions to pass through the membrane) and CLOSED (which does not permit ions to pass through). You have an ion-channel in which the energy of the open state is 600 cal mol-1, the energy of the closed state is 1800 cal mol-1, and the temperature of the system is 300 K. (one cal per mole is equal to 4.18 J per mole, or 6.94×10^−24 J per molecule)

a) Calculate the partition function for this system.

b) What is the probability that the system will be in its open state?

1. A typical ion channel radius is about 1 nm (nanometer), and the thickness of the cell membrane is about 7 nm. The concentration of Na+ ions inside a mammalian heart cell is about 0.6 ions/nm3, and in the fluid surrounding the cell is about 6.0 ions/nm3. The diffusion constant for ions is about 109 nm2/s (nanometers2/second). If the channel were just an open cylinder, how many ions per second would flow through the channel and in which direction?
