Metabolic Biochemistry Name:____________ Winter Quarter 2012 Homework 1 (40 pts.) Section:___________ (Please attach as many sheets of paper as necessary to neatly complete the work) 1) (4 pts.) How does enzymatic catalysis affect the rate constant (k) for the reaction being catalyzed? Explain. How does this affect the velocity of the catalyzed reaction? 2) (4 pts.) How does enzymatic catalysis affect the equilibrium constant for the reaction being catalyzed? Explain. How does this affect the velocity of the catalyzed reaction? 3) (4 pts.) The following chemical reaction was set up and allowed to proceed to equilibrium: compound X compound Y + compound Z Each compound was found to have the following concentration at equilibrium: compound X 8.2 x10 -6 M compound Y 1.7 x10 -2 M compound Z 1.7 x10 -2 M If the forward rate constant (k 1 ) for the reaction equals 128 sec -1 , calculate the value of the reverse rate constant (k -1 ). Show all of your work, and use the correct units on all constants.
