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...

Coulter principle. - The ability to count and measure the size of particles using an electric circuit. Particles are moved through a small aperture, their presence causes a narrowing of the aperture, which leads to an increase in resistance.By using constant I, According to Ohms law (U= I * R), when R increases, U increases and pulse is generated. Parts and functions of the Coulter-counter - - Two spaces with a small aperture in between, capillary (contains the electrolyte solution with the c...
