The protein catalase catalyzes the reaction 2 H 2 O 2 ( aq ) ⟶ 2 H 2 O ( l ) + O 2 ( g ) and has a Michaelis–Menten constant of K M = 25 mM and a turnover number of 4.0 × 10 7 s − 1 . The total enzyme concentration is 0.014 μM and the initial substrate concentration is 4.16 μM . Catalase has a single active site. Calculate the value of R max (often written as V max ) for this enzyme.
