An antibody (Ab) can bind to its antigen binding site (B) with a high affinity (large negative AGO). The antibody and the antigen are mixed at low concentrations and allowed to reach equilibrium. The concentrations measured are [Ab] = 1 nM, [B] = 40 %3D nM, and [Ab-B] = 30 nM, for the equilibrium Ab + B= Ab-B. A. What is the equilibrium constant (association constant), Ką, in M1? B. What is Kd = 1/K, in nM? C. What is AG° in kgT/molecule? Use the equation AG° = -kgTln(Ka) = kgTln(Ka) D. Imagine that this binding were due entirely to hydrogen bonds. Referring to question 3C above, how many hydrogen bonds would form between Ab and B upon binding? E. If you were going to manufacture a coronavirus test kit with an antibody that tightly binds to an antigen found in the virus, would you want the antibody/antigen binding to have a Ka in the nM, µM, or mM range? Why?
Batrachotoxin (C31H42N2O6) is the most potent non-peptide (we'll learn what that means in Lesson 7) based poison known. It gained fame though its use in poison darts made from frog excretions. The frogs themselves don't produce the toxin directly, but through digestion of Melyrid beetles the frogs eat. Suppose you are trekking through the rainforest and discover an even more potent toxin that has the same empirical formula as batrachotoxin. If the molar mass of this new poison is 3,232.02 g/mol, what is its molecular formula?

Glycolysis is the process by which glucose is metabolized to lactic acid according to the equation C6H12O6(aq)2C3H6O3(aq) G=198 kJ at pH 7.0 and 25°C Glycolysis is the source of energy in human red blood cells. In these cells, the concentration of glucose is 5.0103 M, while that of lactic acid is 2.9103 M. Calculate AG for glycolysis in human blood cells under these conditions. Use the equation G=G+RT In Q, where Q is the concentration quotient, analogous to K.
