Oxyanion - Study guides, Revision notes & Summaries

BCH 361 EXAM 2 QUESTIONS WITH ALL VERIFIED ANSWERS What is the purpose of the oxyanion hole in chymotrypsin? - Answer-The oxyanion hole is a structure at the active site of chymotrypsin that stabilizes the tetrahedral intermediate in the proteolysis reaction and facilitates the formation of the acyl-enzyme intermediate. What caused a "burst" of activity followed by a steady-state reaction when chymotrypsin was studied in the milliseconds subsequent to mixing the enzyme and substrate? - An...

• Electrolysis is the decomposition of a compound into its elements by an electric current; usually carried out in an electrolysis cell: • In the electrolysis cell:  The electrolyte is the compound being decomposed, either molten ionic compound or a concentrated aqueous solution of ions  The electrodes are rods, made from carbon or metal, which conducts electricity to and from the electrolyte:  Anode: positive electrode (oxidation)  Cathode: negative electrode (reduction...
