The active form of the enzyme alcohol dehydrogenase exists as a homotetramer (MW = 150 kDa), and has one identical active site located on each of its four subunits. You have performed a series of enzyme kinetic experiments using 0.025 mL of an enzyme sample that is 4.0 µg/mL and determined that the following Vmax = 2.442 x 102umoles/min What is the turnover number of this enzyme (in units of #/sec)?
