WebNov 24, 2024 · Atropine yielded a pA2 value of 8.60 +/- 0.08. How are pA2 and affinity related? The pA2 is a measure of the affinity of a competitive antagonist for its receptor. The determination of the pA2 is made from experiments in which a fixed concentration of the antagonist is used along with graded concentrations of an agonist acting on the same … WebAtropine was shown to disrupt the contractile effect of carbochol, by partially blocking the muscarinic receptors, therefore decreasing its efficacy and preventing it from producing a maximal response in the ileum tissue. However, it should be noted that these results may lack reliability due to the time constraints of the study. Bibliography perkies coffee haus https://ifixfonesrx.com
