What is an advantage of increasing the catalytic rate of enz
     What is an advantage of increasing the catalytic rate of enzymes in cold environments?  Select one:  Temperature compensation of metabolism  There is a high metabolic cost to maintaining a high K_cat  There is a high metabolic cost to producing more enzymes  The binding ratio doesn\'t matter 
  
  Solution
ANS: B. There is high metabolic cost to maintain a high Kcat.
Explanation:
Kinetic energy is used to measure the temperature of system. In lower temperature, the Kinetic energy is low and the substrates turned over rate is reduced (Kcat). For increasing Kcat can cause high metabolic cost, so increasing catalytic rate can reduce high metabolic cost.
