Grade 12 Biochemistry Test Review Graded A+ In which organelle does the majority of ATP production occur during cellular respiration? Mitochondria What is the significance of the R-group (side chain) in an amino acid? The R-group determines the unique properties and functions of each amino acid. What happens when a protein denatures? The protein loses its three-dimensional structure and can no longer function properly. How does a phospholipid's structure make it ideal for...

Which of the following is expected to appear in excess in the body of a patient with inherited homocystinuria? ANS Methionine - know the 20 common amino acids, in this disease the cysteine synthesis pathway is blocked so the answer is not C, which is cysteine. glycine and arginine are not mentioned in the passage, so they are incorrect. Both methionine and homocysteine would be found in excess and only methionine is an answer choice homocystinuria may present in cases of vitamin defic...

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...
