From a kinetics experiment, kcat was determined to be 3.5 x 103sec-1.  For the

kinetic assay, 0.15mL of a 0.5mg/mL solution of enzyme was used, and the enzyme has a molecular weight of  45,000 g/mole.  Assume a reaction volume of 3mL.  Calculate Vmax (µM∙min-1) for the enzyme and catalytic efficiency ( in M-1sec-1) for the enzyme. The Kmfor the enzyme was determined to be 6.5 x 10-2M.
