In a certain kinetics experiment, the enzymatically catalyzed hydrolysis of ATP proceeds at a constant rate of 2.0 µM•s-1. If the volume of solution is 1.0 mL, what is the total number of ATP molecules that hydrolyzed after 1 min?

Rate of hydrolysis = 2 x 10⁻⁶ M per second = 2 x 10⁻⁶ x 60 M per minute

2 x 10⁻⁶ x 60 x 6.03 x 10²³ molecules per minute

= 723.6 x 10¹⁷ molecules/min.
