The correct answer is: The number of substrate molecules that a molecule of an enzyme convert into products per minute
The number of substrate molecules changed per minute by a molecule or enzyme is called turn over number. The higher the turn-over number, the more efficient an enzyme is. It depends upon the number of active points present over an enzyme, precise collisions between reactants and the rate of removal of end products.
