12) At physiological pil. which amino acids act as axial heme iron ligands to cytochrome c? Illustrate which atoms of these amino acids form coordinate bonds to the hcme iron. The axial ligands on cytochrome c are methionine and histidine. The sulphur of methionine and nitrogen of histidine form coordinate bonds to the iron of heme unit. 13) In the absorbance spectrum of ferric cytochrome ca weak absorbance band is observed at 695 nm. Which axial ligand to the heme iron is this zbsorbance band associated with?

I did not understand soultion for the question.. The relationship between Affinity and Association & Dissociation Constant. Four proteins (A-D) all bind the same ligand (X), with different affinities. For protein A & B we know that they have a binding site for X with a Kd (dissociation constant) of 10⁻⁵and 10⁻⁸ M, respectively. For protein C and D we know that they have a binding site for ligand X with a Ka (association constant) of 10³and 10⁵M, respectively. Which protein has the highest affinity for ligand ? Explain your reasoning. How do you make them all in same constant so that values can be compared and the one with highest Ka or lowest Kd (Highest affinity in both cases) can be ruled out.
