The enzyme urease enhances the rate of urea hydrolysis at pH 8.0 and 20oC by a factor of 1014. If a given quantity of urease can completely hydrolyze a given quantity of urea in 5.0 min at 20oC and pH 8.0, how long would it take for this amount of urea to be hydrolyzed under the same conditions in the absence of urease?

When enzyme solutions are heated, there is a progressive loss of catalytic activity over time due to denaturation of the enzyme. A solution of the enzyme hexokinase incubated at 45oC lost 50% of its activity in 12 min, but when incubated at 45oC in the presence of a very large concentration of one of its substrates, it lost only 3% of its activity in 12 min. What is correct explanation
