Unformatted text preview: AMATH/BIOL 382 Problem Set 2 Due February 3, 2010 1. Recall the derivation of the MichaelisMenten description of an enzyme catalysed reaction (refer to Figure 1). If the back reaction C ← P + E is not assumed negligibly slow, the k 1 k1 k 2 k2 C E + P S + E . Figure 1: enzymecatalysed reaction analysis needs to be extended. a) Write down a complete description of the system dynamics ( not assuming k 2 = 0). b) Making the quasisteady state assumption, show that c = k 1 e s + k 2 e p k 1 s + k 2 p + k 1 + k 2 c) Determine the overall reaction rate (i.e. the net rate of production of product) as a function of the concentrations of substrate and product. d) Confirm that when k 2 is taken to be zero, the standard form for MichaelisMenten kinetics is recovered. 2. a) How would you estimate the MichaelisMenten parameters V max and K m from a LineweaverBurke plot : a linear plot of 1 /V against 1 /s (where V is the rection rate, or velocity)....
