Based on the "Data from the Experiment" table, what is the maximum rate of increase in inorganic phosphate P i concentration observed during the experiment?

  • A: 2 µmol/(mL·min)
  • B: 12 µmol/(mL·min)
  • C: 16 µmol/(mL·min)
  • D: 18 µmol/(mL·min)

Explanation

To find the rate, calculate the change in P i concentration over each 5-minute interval: Concentration final - Concentration initial / Time final - Time initial . The highest rates are observed between 10-15 minutes 180-90 /5 = 18 and 15-20 minutes 270-180 /5 = 18 .
