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
