With reference to enzymes, turn over number means substrate molecules converted into products per

• A. Hour
• B. Second
• C. Minute
• D. Day

Answer 1

The correct option is B Second

With reference to enzymes, turn over number means substrate molecules converted into products per second when the concentration of substrate is at saturation. It helps to estimate the efficiency of an enzyme. It is calculated by the ration of V${}_{max}$ and catalyst site concentration. For example if the turover value of an enzyme is 60,000 it means it can produce 60,000 product molecule per second at a particular catalytic site.

So, the correct answer is option B.
