3. In the previous problem, we assumed that we knew each protein conformation corresponded to one unique state. Normally, you do not have this information a priori. Let's say that Nopen and Nclosed states exhibit open and closed conformations, respectively. (In other words, the open and closed energy levels have a degeneracy of Nopen and Nclosed, respectively.) A) Find the fraction of time that a protein is in an open conformation, in terms of Nopen,Nclosed,T, and the difference in energies between the two conformations. B) At 300K, the protein is in the open conformation 60% of the time. At 310K, this fraction rises to 65%. Find the difference in energy levels, again in molar units. C) Find the ratio Nopen/Nclosed
