1. The nucleus , which is essential for function and survival of the cell. A) is the site of protein synthesis B) contains the genetic code C) transforms cellular energy D) initiates aerobic metabolism 2. Although energy is not made in mitochondria, they are known as the powerplants of the cell because they: A) contain RNA for protein synthesis. B) utilize glycolysis for oxidative energy. C) extract energy from organic compounds. D) store calcium bonds for muscle contractions. 3. Alth...

Comprehensive CRNA Interview Review Accurate responses are given. Comprehensive CRNA Interview Review Norepinephrine Mechanism of Action (MOA) A1, A2, B1 agonist. Primary agent used in distributive shock because it's ability to recruit venous volume and augment preload, while increasing arterial tone, and increasing cardiac output. Alpha one causing peripheral smooth muscle contraction. (low dose venous, high dose venous and arterial). Alpha 2 adrenoreceptor agonism actually ant...

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...
