Which of the following statements are correct for the Kcat?
A. It is also called turnover number
B. Specificity constant of an enzyme can be calculated from its Kcat and Km
C. Kcat is calculated from the Vmax and number of substrate binding site of an enzyme

Choose the correct answer from the options given below:

Statement I: The binding site on the enzyme is known as the active site and is structurally complementary to the substrate.
Statement II: Binding of a substrate to an enzyme active site causes a change in the three-dimensional structure of the enzyme which helps to reduce the activation energy of the reaction.
