The enzyme fumarase catalyzes the reaction fumarate H2O rig
     The enzyme fumarase catalyzes the reaction fumarate + H_2O rightarrow malate.  The turnover number for this enzyme and substrate is 800 per minute. How long would it take one molecule of fumarase to produce 7130 product molecules?  Ans:  min 
  
  Solution
turnover number(also termed kcat) is defined as the maximum number of chemical conversions of substrate molecules per second that a single catalytic site will execute for a given enzyme concentration
Ans . 8.915
in 1 min turnover number is 800 then to form 7130 product molecule it will
7130/800= 8.915 min
