Binding is reversible - Study guides, Class notes & Summaries

VCU Biochem Exam 2 Questions And Answers is binding of ligands reversible? - ANS-yes, it is essential for it to be reversible cooperativity - ANS-In multisubunit proteins, conformational changes in one subunit can affect the others functions of globular proteins - ANS-1. storage of ions and molecules (myoglobin and ferritin) 2. transport of ions and molecules (hemoglobin, serotonin transporter) 3. defense against pathogens (antibodies, cytokines) 4. muscle contraction (actin, myosin) 5....

Which of the following is an up-regulation response in drug action? a. depolarization b. hyperpolarization c. increasing excitability of the neurons d. decrease receptor density. e. increase receptor density. - ANS E. Increase receptor density If a drug A mimics the effects of drug B completely, it is a a. full agonist. b. partial agonist. c. full antagonist. d. partial antagonist. e. inverse agonist. - ANS A. Full agonist If a drug A binds to the same binding sit...

active site (biochemistry) - the region of an enzyme that binds to a protein or to another substance during a reaction, where catalytic activity occurs allosteric site (biochemistry) - site at which a small regulatory molecule interacts with an enzyme to inhibit or active that specific enzyme, binding of allosteric effector is in general noncovalent and reversible amino acid (biochemistry / molecular genetics) - a simple organic compound containing a carboxyl group and an amino group am...

when cells respond to an extracellular signal, they most often convert the information carried by this molecule from one form to another. What is this process called? - Answer-signal transduction When does signal transduction begin? - Answer-when the receptor on a target cell recieves and incoming extracellular signal and then produces intracellular signaling molecules that alter cell behavior extracellular signal molecules, released locally example: inflammation regulation at site of infe...

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...
