Yes.  If I have the fraction a/a, that is equal to 1, correct?  So if ( k2 + k3) appears in both the top and bottom of a fraction, they also equal one, and they can be cancelled out.  And so forth.

You are welcome.  I think that there are some take-home messages from your problem.  One is that Kd and KM are not the same thing.  Another is that the definitions of kcat and KM depend on the particulars of the kinetic model.  Students of enzyme kinetics might also wish to derive the rate equation for this mechanism from steady-state principles.
