O Increasing blood pH results in more oxygen unloading in tissues. O Hemoglobin has a lower affinity for oxygen under high temperature conditions. O The greatest delivery of oxygen from the blood to the surrounding tissues occurs at 37C.

Two proteins bind to the same ligand, and protein A has a fractional saturation of 0.5 when the ligand concentration is 0.5 mM, while protein B has a fractional saturation of 0.25 at 0.3 mM of the ligand. Which protein binds the ligand more strongly, and what is the dissociation constant for that protein-ligand interaction? *** I know the answer I just need the steps to do it*** Answer: Protein A binds more strongly, and Kd = 0.5 mM.
