BMEN 289 Engineering Biology Homework Set #2 Due Tuesday, Sept. 28 1. The rate equations from the handout (Equations 2-4) still apply, but now Equation 2 is set to zero: dC S /dt = -k 1 C E C S + k -1 C ES = 0 Now K D* = k -1 / k 1 = C E C S / C ES Solving for C E and inserting into the balance on the enzyme gives, So, * * 0 0 * K K + + K D ES D S E E ES ES ES S S E S ES D S C C C C C C C C C C C C C + = = = = + From Equation 8, 0 max 2 2 * * E S S ES D S D S dP C C V C V k C k dt K C K C = = = = + + so K M = K D*
