Quiz 5 for Physics 176 Professor Greenside Thursday, April 8, 2010 This quiz is closed book and no calculators or any other electronic devices are allowed. Please write all answers on the supplementary blank pages. Also, write your name and problem number on each extra page. The following equations may be useful: E =- ln( Z ) , Z N = Z N 1 N ! , Z 1 = V Z int V Q , V Q = h 2 mkT 3 . (1) E = X s E ( s ) p s , p s = e- [ E ( s )- A N A ( s )- B N B ( s )] Z , Z = X s e- [ E ( s )- A N A ( s )- B N B ( s )] . (2) 1. (10 points) A certain olfactory receptor in your nose has three slots such that one slot can bind a single molecular odorant of type A with energy E A < 0, while each of the other two slots can independently bind a single molecular odorant of type B , with binding energy E B < 0. (The energy of the receptor is zero if nothing binds to it, and the receptor can bind up to three molecules.) Theof the receptor is zero if nothing binds to it, and the receptor can bind up to three molecules....
