Lecture 9 What is the energy of activation delta G knot double dagger? Correct Answer-it is the Energy difference between going from the ground state at the beginning to this high energy state which represents by the transition state what is the delta delta G knot double dagger? Correct Answer-which a reflection of how effective an enzyme which lowers the overall energy of activation. True Correct Answer-T/F Enzymes do not change the Final equilibrium state. But it does help to get int...

Tri 1 Biochem Past Exams Questions and Answers Already Passed What is the role of zinc in enzyme function? Zinc acts as a cofactor, stabilizing the structure of enzymes and aiding in catalysis. Which type of bond forms between the amino group of one amino acid and the carboxyl group of another? A peptide bond forms between the amino and carboxyl groups, linking amino acids together. How do enzymes use the lock-and-key model to explain substrate binding? The lock-and-key model ...

Dr Rai biochem test 2 questions & answers 2023/2024 kinetic mechanism - ANSWER-the order of binding of substrates and release of products sequential mechanism - ANSWER-each substrate binds but both substrates must be bound by enzyme to form a ternary complex before catalysis can occur ping pong mechanism (double displacement) - ANSWER-Substrate binds to the enzyme and releases a product before the second substrate binds to the enzyme Random order enzyme mechanism - ANSWER-any react...

tbr- enzyme kinetics exam questions & answers 2024 allosteric enzyme - ANSWER-often have multiple inhibitor or activator binding sites to change conformation, switching between active and inactive shapes allosteric curve - ANSWER-sigmoidal shape ex. hemoglobin = allosteric protein transition state analogs - ANSWER-synthesized compounds that mimic the form of the transition state of a substrate molecule and binds to the enzyme to inhibit catalysis rxn transition state vs intermedi...
