Adrienne’s doctor prescribed a new medication for her to take. the drug is affecting the leakage channels in her neurons. which of the following statements is false? a) adrienne’s neurons will function just as well as before, as the sodium-potassium pump will take over for the leakage channels. b)  adrienne’s neurons will not be able to maintain the delicate balance necessary to keep her cells right at the resting membrane potential. c) adrienne’s neurons will likely die because there is no other way for sodium or potassium to enter or leave the cell other than through the channels. d)  adrienne’s neurons will likely adapt to the medication and enable her neurons to no longer need her leakage channels for the resting membrane potential.

Match the descriptions / definitions with the term they best describe 1. three dimensional relationship of the different polypeptide chains in a multisubunit protein or protein complex 2. common folding pattern in proteins in which a linear sequence of amino acids folds into a right-handed coil stabilized by internal hydrogen-bonding between polypeptide backbone atoms. 3. the amino acid sequence of a protein 4. a region on the surface of a protein that can interact with another molecule through noncovalent bonding. 5. three-dimensional arrangement of alpha-helices and beta-sheets within a single polypeptide, typically stabilized by a variety of noncovalent bonds, including ionic and hydrogen bonds, and nonpolar interactions / hydrophobic force. 6. the chain of repeating carbon and nitrogen atoms, linked by peptide bonds, in a protein. 7. common structural motif in proteins in which different sections of the polypeptide chain run alongside each other and are joined together by hydrogen bonding between atoms of the polypeptide backbone. 8. portion of a polypeptide chain that has a discrete tertiary structure of its own and can often fold independently of the rest of the chain 9. regular local folding patterns in a protein, including alpha-helix and beta-sheet a. primary structure b. beta-sheet c. protein d. coiled-coil e. polypeptide backbone f. secondary structure g. side chain h. tertiary structure i. binding site j. alpha-helix k. quaternary structure l. protein domain
