Name:
The enzyme carbonic anhydrase catalyzes both directions of the reaction
A study of the conversion of carbon dioxide to carbonic acid by a
2.32nmol/L solution of carbonic anhydrase yielded the
following initial rate data:
[CO2] (mmol/L) |
1.25 |
2.50 |
5.00 |
20.00 |
v (
) |
![$2.78\times 10^{-5}$](img3.gif) |
![$5.00\times 10^{-5}$](img4.gif) |
![$8.33\times 10^{-5}$](img5.gif) |
![$1.66\times 10^{-4}$](img6.gif) |
Calculate KM and k-2 (the rate constant for the step
)
for this enzyme.
Note: Drawing a graph is optional.
