An experiment is designed to study the differences between two tissue-specific isozymes of a particular enzyme. The Vmax, of enzyme 1 is 300 units of activity per minute per milligram of protein, whereas the Vmax of enzyme 2 is 30 units of activity per minute per milligram of protein. Based on these numbers, which of the following conclusions about the K,. values for enzyme 1 and enzyme 2 is most accurate?

A) The Km. cannot be predicted based solely on the value of Vmax.
B) The Km for enzyme 1 and the Km for enzyme 2 will differ but cannot be quantified with the given data.
C) The Kmax for enzyme 1 is one-tenth the Km enzyme 2
D) The Kmax for enzyme 1 is ten times greater than the Km for enzyme 2
E) They are the same
