An enzyme-catalyzed reaction was carried out with the substrate concentration initially 1,000 times greater than the Km for that substrate. After nine minutes 1% of the substrate had been converted to the product as well as the amount of product formed was 12umol. If in a separate experiment, 1/3 as much enzyme as well as twice as much substrate had been combined, explain how long it would take for the same amount of product to be formed?
