A 54-yeаr-оld pаtient is аdmitted with cоmmunity-acquired pneumоnia. The provider orders ceftriaxone (Rocephin) 2 g IV, to be diluted in 50 mL of 0.9% normal saline and infused over 30 minutes. The nurse must regulate the infusion manually using gravity tubing with a drop factor of 15 gtt/mL. Calculate the flow rate in gtt/min. Round to the nearest whole number. Enter numeric value only.

It is numerically equal to the substrate concentration required to achieve one half the maximum velocity. b. Its defined as Km = k1/(k−1 + k2). c. It is approximately equal to the dissociation constant for the enzyme-substrate complex to E + P. d. The value of Km is constant for an enzyme regardless of the specific substrate molecule used to determine it. e. Its numeric value has the units of moles−1.
