BCH 403 EXAM 1 Questions with Complete Solutions
PeptideT or F? Peptide bonds behave as rigid planes because of partial double-bond character between the carbonyl carbon of one residue and the amide hydrogen of another residue. Correct Answer-FAlSE! B/C Hydrogen can't have a double bond, but if it stayed nitrogen it would be true. T or F? The process by which hydrophobic molecules are driven together, therefore maximizing the entropy of water, is referred to as the Hydrophobic effect. Correct Answer-TRUE! The strong electronegativity is responsible for the lack of H-bonding for molecules that contain hydrocarbons. T or F? Correct Answer-FALSE! Carbon isn't strongly electronegative. The Henderson-Hasselbalch equation is only able to calculate fractional ionization of an amino acid when the pH is qual to the pKa. T or F? Correct Answer-FALSE! pH= pKa + log([A-]/[HA]) Intrinsically disordered proteins retain little structure beyond primary or secondary structure. T or False? Correct Answer-TRUE! Which of the following is not true regarding a biochemical reaction: A) A positive delta G means that the reaction will never reach an equilibrium. B) A negative delta G means that th
