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...

Receptor Macromolecule whose biological function changes when a drug binds to it What are the link between chemical actions and biological function? Receptors Emax maximum effect of a drug What happens when Emax is reached? Emax occurs when all receptors are bound What is in indication that spare receptors are present? When Emax is reached before all receptors are bound Agonist has affinity for a receptor as well as intrinsic activity at the receptor ...

False - correct answer True or False: an antagonist will behave in a similar manner to an endogenous substrate An antagonist blocks an endogenous substrate from binding to its receptor - correct answer How does an antagonist work? Bronchial Smooth Muscle Relaxation - correct answer Activation of B2-receptors in the lungs would produce what effect? Reduced Heart Rate and Contractility - correct answer Antagonism of B1-receptors in the heart would produce what effect? Enzymes catalyze ...

Competitive Antagonists correct answer: Compete with neurotransmitters for access to orthosteric binding sites on receptors *block responses to agonists How do competitive antagonists affect DRC? correct answer: Cause a rightward shift How do you reverse the effects of a antagonists? correct answer: Add more exogenous agonist or increase the concentration of endogenous for that receptor in order to overcome that antagonism When an antagonist competes with an agonist, does the anta...
