An enzyme has velocities of 0.11 nmol/min at a substrate concentration of 1 μM, 0.34 nmol/min at a substrate concentration of 5 μM, and 0.45 nmol/min at a substrate concentration of 10 μM. What is the Vmax for the enzyme if the KM is 5 × 10–6 M?
A.
0.22 nmol/min
B.
0.68 nmol/min
C.
0.90 nmol/min
D.
1.12 nmol/min
