Question: A ligand binds two different receptors with a K d value of 10 -7 M for receptor l and a K d value of 10-

A ligand binds two different receptors with a K_d value of 10^-7 M for receptor l and a K_d value of 10-⁹ M for receptor 2. For which receptor does the ligand show the greater affinity? Calculate the fraction of receptors that have a bound ligand (IRL] / Rr) in the case of receptor 1 and receptor 2 if the concentration of free ligand is 10^-8 M.
