The enzyme urease increases the rate of urea hydrolysis at pH 8.0 and 20 °C by a factor of 10¹⁴. Suppose that a given quantity of urease can completely hydrolyze a given quantity of urea in 19 minutes at pH 8.0 and 20 °C. How long would it take for this amount of urea to be hydrolyzed in the absence of urease at the same temperature and pH in sterile conditions? Include two significant figures in your answer.
