With reference to enzymes, turn over number means
Options
- AThe number of substrate molecules that a molecule of an enzyme converts into products per hour
- BThe number of substrate molecules that a molecule of an enzyme converts into products per second
- CThe number of substrate molecules that a molecule of an enzyme convert into products per minute
- DThe number of substrate molecules that a molecule of an enzyme converts into products per day
Correct answer
C. The number of substrate molecules that a molecule of an enzyme convert into products per minute
Step-by-step solution
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.
