competitive antagonist correct answer: an agonist that "competes" for the same binding site as another substance only blocks endogenous ligand, cannot activate receptor reversible competition Competitive antagonists cause a _____ shift in the drug response curve correct answer: rightward T/F: Competitive antagonism can be surmounted by adding more agonist correct answer: True! With enough agonist, you can flood the receptors so that the angonist out competes the competitive antagon...
