You measure the rate of an enzyme-catalyzed reaction at different initial substrate concentrations under Michaelis-Menten conditions. Assuming you have knowledge of the concentration of enzyme in the reaction, which of the following parameters can be estimated from the results of these measurements? A. The maximal velocity of the enzyme at saturating substrate concentrations. B. (k-1 + k2)/k1 C. The turnover number. D. All of the above.
An enzyme has a Km for substrate of 10 mM and Vmax of 5 µmol L-1 sec-1 at a total enzyme concentration of 1 nM. At [S] = 10 mM, kcat is: A) 2500 per M per sec. B) 5000 per M per sec. C) 1250 per M per sec. D) 2500 per sec. E) 5000 per sec.
