Direction: An enzyme (24000 Da) undergoes first-order deactivation kinetics while catalyzing a reaction according to Michaelis-Menten kinetics (Km= 10–4 M). The enzyme has a turnover number if 104 molecules substrate/min-(molecule enzyme) and a deactivation constant (kd) of 0.1 min–1 at the reaction conditions. The reaction mixture initially contains 0.6 mg/l of active enzyme and 0.02 M of the substrate.

    1. 16 min
    2. 24 min
    3. 32 min
    4. 8 min
