Statistical Study of Oxygen Binding to a Heme protein 2017-03-05 Copy , 2of7 In this exercise, we will use partition functions and statistical techniques to charaterize the binding equilibrium of oxygen to a heme protein. The equilibrium that we study is O2(gas, 310K)+02(bound, 310K). Give all answers to three significant figures. Part A Calculate the thermal wavelength (also called the deBogle wavelength) for diatomic oxgen at T-310K. 75x10-11m Previous Answers Correct Part B Calculate the rotational partition function of oxygen at T-310K. Remember, O2 is a homonuclear diatomic molecule. Assume the roational temperature of O2 is e rof-2.07K. a_(rot) = 74.9 Previous Correct Part C Calculate the bond vibrational partition function of oxygen gas at T-310K. Assume the vibrational temperature of oxygen gas is Bviblgas)-2260K. | q(vib.gas)= 2.61x10-2

Explanation / Answer

Solution:

F and G. I don't have an idea how to calculate the binding constant but if you can get the binding constant value, it's easy to answer H and I as shown below.

H.

Go = -RTlnK

Here, R = 8.314*10-3 KJ.mol-1.K-1. and T = 310 K

And you need to substitute the K value obtained as an answer in Question 'G'.

I.

f = K / (1 + K)

Here also, you need to substitute the K value obtained as an answer in Question 'G'.

All the best to find the binding constant value and proceed further!!!
