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...

Biochemistry Test 1 Questions and Answers Graded A+ What is the role of allosteric sites in enzyme regulation? Allosteric sites are regions where molecules can bind and influence enzyme activity by changing its shape. How do competitive inhibitors affect enzyme function? Competitive inhibitors compete with substrates for binding at the active site, reducing enzyme activity. What determines the tertiary structure of a protein? The tertiary structure is determined by interactio...

How do most enzymes reduce the activation energy needed to move a reaction forward? - Ans Providing an active site most complementary the transition state An enzyme has a mutation within the substrate binding of the coenzyme needed for covalent catalysis. Which of the following is likely to result as a consequence of this mutation? - Ans The enzyme will not be able to form the transition state complex

Biochemistry Final Exam Questions and Answers Already Passed What role do protein domains play in enzyme function? Protein domains allow enzymes to perform specific functions, often facilitating interactions with other molecules or substrates. How do post-translational modifications affect protein behavior? They can alter protein activity, localization, and stability, enabling dynamic responses to cellular signals. What is the significance of the "lock and key" model in e...

What is cellular metabolism? - a controlled set of biochemical reactions that occur in living organisms in order to maintain life What is an enzyme? - a protein, or group of proteins, that catalyze (speed up) chemical reactions What is unique about enzymes? - the enzyme is not consumed during the reaction and can be used repeatedly by the cell What is a cofactor? - a small chemical component, usually metal ions, that assist enzymes during the catalysis reactions
