Discussion:
Determining Activation Energy from Rate Constant for an Enzyme-Catalyzed Reaction
Here is the problem I have to solve:
If 10 g of pure carbonic anhydrase catalyzes the hydration of 0.30 g of carbon dioxide in 1 min at 37 degrees C under optimal conditions, what is the turnover number (kcat) of carbonic anhydrase (in units of min-1)?
I have already calculated the turnover number, which is 2.0 x 107 min-1, but I'm kind of lost with two other questions.
(b) From the answer in (a) calculate the activation energy of the enzyme catalyzed reaction (in kJ/mol)
(c) If carbonic anhydrase provides a rate enhancement of 107, what is the activation energy for the uncatalyzed reaction?
