(Amin) Figure belоw shоws the drug X cоncentrаtion-response relаtionship for receptor NH (shown in bold) within а tissue culture isolated from lungs. In the presence of 1, 3, or 5 µM of drug Q (dash lines), the EC50 of drug X shifts to the higher concentrations with no change in the maximal (dash lines). However, in the presence of higher concentrations of Q (10, 20, 50, 100, or 300 µM), there is an insurmountable decrease in the maximal effect. What is the reason behind the unique pattern in the shift of drug X concentration-response relationship (first, a shift with in the EC50 and second, a reduction in the maximal effect) in the presence of increasing concentrations of drug Q in this tissue? (6 points). What is the nature of Drug Q (agonist, competitive antagonist, etc)? (3 points)
