entropy

Hi SDN! I was wondering what the relationship between cooperativity and entropy is with regards to hemoglobin and oxygen binding. I came across a question in TPR biochem review on this topic and in the answer description it says "consistent with the 'cooperativity' phenomenon of each of these...

I'm having some difficulty understanding this problem from my Kaplan full length. (pic attached) I would think that because the non-polar proteins are clustering (much like folding the non-polar R-groups inwards) that it is becoming more ordered and thus entropy would be decreasing. Also, I...

I know that 1. Entropy decreases from Gas > Liquid > Solid 2. 2 moles of a substance has more entropy than 1 mole 3. Greater molar mass/complexity means more entropy Is there anything else I am missing? This Khan Q said Na+ (aq) has greater entropy than PO3-4 (aq) because "Solvating ions...

I read that that for dG and dH, there is a standard pressure, but NO standard temperature. Q1-Why not? Q2-So...things don't change based on temperature? So in dG=dH-TdS, this relationship will hold true no matter the temperature? How can that be...dG and dH have fixed values, and the entropy...
